-/**
- * Eviction algorithm that uses a key in the Node data that indicates the time
- * the node should be evicted. The key must be a java.lang.Long object, with
- * the time to expire as milliseconds past midnight January 1st, 1970 UTC (the
- * same relative time as provided by {@link
- * java.lang.System#currentTimeMillis()}).
- * <p/>
- * This algorithm also obeys the configuration key {@link
- * org.jboss.starobrno.eviction.ExpirationAlgorithmConfig#getMaxNodes()}, and will evict the soonest to
- * expire entires first to reduce the region size. If there are not enough
- * nodes with expiration keys set, a warning is logged.
- * <p/>
- * If a node in the eviction region does not have an expiration value, then
- * {@link org.jboss.starobrno.eviction.ExpirationAlgorithmConfig#getTimeToLive()} (if set) will be used.
- * The expiration is updated when a node is added or updated.
- * <p/>
- * If there is no time-to-live set, and a node in the eviction region does not
- * have an expiration value, then that node will never be evicted. As
- * forgetting to indicate an expiration value is likely a mistake, a warning
- * message is logged by this class. This warning, however, can be disabled
- * through {@link org.jboss.starobrno.eviction.ExpirationAlgorithmConfig#setWarnNoExpirationKey(boolean)}.
- * <p/>
- * A node's expiration time can be changed by setting a new value in the node.
- * <p/>
- * Example usage:
- * <pre>
- * Cache cache;
- * Fqn fqn1 = Fqn.fromString("/node/1");
- * Long future = new Long(System.currentTimeMillis() + 2000);
- * cache.put(fqn1, ExpirationConfiguration.EXPIRATION_KEY, future);
- * cache.put(fqn1, "foo");
- * assertTrue(cache.get(fqn1) != null);
- * <p/>
- * Thread.sleep(5000); // 5 seconds
- * assertTrue(cache.get(fqn1) == null);
- * <p/>

-/**
- * Least Frequently Used algorithm for cache eviction.
- * Note that this algorithm is not thread-safe.
- * <p/>
- * This algorithm relies on maxNodes and minNodes to operate correctly.
- * Eviction takes place using Least Frequently Used algorithm. A node A
- * that is used less than a node B is evicted sooner.
- * <p/>
- * The minNodes property defines a threshold for eviction. If minNodes = 100,
- * the LFUAlgorithm will not evict the cache to anything less than 100 elements
- * still left in cache. The maxNodes property defines the maximum number of nodes
- * the cache will accept before eviction. maxNodes = 0 means that this region is
- * unbounded. minNodes = 0 means that the eviction queue will attempt to bring
- * the cache of this region to 0 elements (evict all elements) whenever it is run.
- * <p/>
- * This algorithm uses a sorted eviction queue. The eviction queue is sorted in
- * ascending order based on the number of times a node is visited. The more frequently
- * a node is visited, the less likely it will be evicted.

+ * The minNodes property defines a threshold for eviction. If minNodes = 100,

+ * still left in cache. The maxNodes property defines the maximum number of nodes
+ * the cache will accept before eviction. maxNodes = 0 means that this region is
+ * unbounded. minNodes = 0 means that the eviction queue will attempt to bring
+ * the cache of this region to 0 elements (evict all elements) whenever it is run.
+ * <p/>
+ * This algorithm uses a sorted eviction queue. The eviction queue is sorted in
+ * ascending order based on the number of times a node is visited. The more frequently
+ * a node is visited, the less likely it will be evicted.

- <title>General Information</title>
-
- <qandaentry>
- <question id="a49">
- <para>What is POJO Cache?</para>
- </question>
-
- <answer>
- <para>POJO Cache is a fine-grained field-level replicated and
- transactional POJO (plain old Java object) cache. By POJO, we mean
- that the cache: 1) automatically manages object mapping and
- relationship for a client under both local and replicated cache
- mode, 2) provides support for inheritance relationship between
- "aspectized" POJOs. By leveraging the dynamic AOP in JBossAop, it is
- able to map a complex object into the cache store, preserve and
- manage the object relationship behind the scene. During replication
- mode, it performs fine-granularity (i.e., on a per-field basis)
- update, and thus has the potential to boost cache performance and
- minimize network traffic.
- </para>
-
- <para>From a user perspective, once your POJO is managed by the
- cache, all cache operations are transparent. Therefore, all the
- usual in-VM POJO method semantics are still preserved, providing
- ease of use. For example, if a POJO has been put in POJO Cache (by
- calling
- <literal>attach</literal>
- , for example), then any POJO get/set
- method will be
- intercepted by POJO Cache to provide the data from the
- cache.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a1">
- <para>What is the relationship between Core Cache and POJO Cache?</para>
- </question>
-
- <answer>
- <para>Cores Cache is a traditional generic distributed cache system.
- POJO Cache uses Core Cache as the underlying distributed state system to achieve object caching.
- As a result, all the replication aspects are configured with the Cache configuration XML.
- Additionally, POJO Cache also has API to expose the Cache interface (via
- <literal>getCache()</literal>
- API).
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a52">
- <para>What is the difference between Core Cache and
- POJO Cache?
- </para>
- </question>
-
- <answer>
- <para>Think of POJO Cache as a Cache on steroids. :-)
- Seriously, both are cache stores-- one is a generic cache and the other other one POJO Cache.
- However, while Cache only
- provides pure object reference storage (e.g.,
- <literal>put(FQN fqn,
- Object key, Object value)
- </literal>
- ), POJO Cache goes beyond that
- and performs fine-grained field level replication object mapping and
- relationship management for a user behind the scenes. As a result,
- if you have complex object systems that you would like to cache, you
- can have POJO Cache manage it for you. You simply treat your
- object systems as they are residing in-memory, e.g., use your
- regular POJO methods without worrying about cache management.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a521">
- <para>How does POJO Cache work then?</para>
- </question>
-
- <answer>
- <para>POJO Cache uses the JBoss AOP project to perform field level
- interception. This allows POJO Cache to monitor changes to your object model, and react
- accordingly.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a522">
- <para>What's changed between 1.x and 2.x release then?</para>
- </question>
-
- <answer>
- <para>Starting in 2.0 release, we have a separate library for POJO Cache,
- <literal>pojocache.jar</literal>
- that
- is extra to the core
- <literal>jboss-cache.jar</literal>
- . Since we uses Cache as a delegate, user
- will need to have a regular xml to configure the core Cache functionality (e.g., replication and locking
- aspect). In addition, there is also the
- <literal>pojocache-aop.xml</literal>
- that specifies the POJO Cache
- interceptor stack (that can be left as default).
- </para>
- <para>Additionally, here are the changed features:
- <itemizedlist>
- <listitem>
- <para>New APIs. It replaces
- <literal>putObject, removeObject, and get</literal>
- with
- <literal>attach, detach, and find</literal>
- .
- </para>
- </listitem>
- <listitem>
- <para>New POJO based events that a user can subscribe to.</para>
- </listitem>
- <listitem>
- <para>New configuration pojocache-aop.xml specifically for POJO Cache, in addition to
- the regular cache-service.xml for the delegating Cache.
- </para>
- </listitem>
- <listitem>
- <para>New package namespace (
- <literal>org.jboss.cache.pojo)</literal>
- for POJO Cache.
- The previous
- <literal>org.jboss.cache.aop</literal>
- space has been deprecated.
- </para>
- </listitem>
- </itemizedlist>
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a53">
- <para>How do you use POJO Cache?</para>
- </question>
-
- <answer>
- <para>In order to use POJO Cache, you will need to:</para>
-
- <itemizedlist>
- <listitem>
- <para>Annotate your POJOt with @Replicable.
- </para>
- </listitem>
- <listitem>
- <para>Instrument your POJO. This can be done at load-time using special JVM arguments (prefered), or at compile time using the
- AOP precompiler tool (aopc). See the user guide for more specific details on instrumentation.
- </para>
- </listitem>
- </itemizedlist>
- </answer>

- <question id="a541">
- <para>What is the JDK version required to run POJO Cache 2.x?</para>
- </question>
-
- <answer>
- <para>POJO Cache 2.x requires Java 5 or newer.</para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a542">
- <para>Can I run POJO Cache as a standalone mode?</para>
- </question>
-
- <answer>
- <para>Yes, same as the Core Cache library, you can run POJO Cache either as a standalone or
- inside an application server.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a543">
- <para>What is the JBoss AS recommended version to run POJO Cache 2.x?</para>
- </question>
-
- <answer>
- <para>POJO Cache can be run either in AS4.0.5 (and up) and 5.0. But either way, it will require
- JDK5.0 though.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a56">
- <para>Can I pre-compile objects used in POJO Cache, so that I don't have to provide an AOP descriptor?
- </para>
- </question>
-
- <answer>
- <para>Yes. The AOP library included with POJO Cache has a pre-compiler called
- <literal>aopc</literal> that can be used to instrument objects in advance. However,
- this is not the recommended approach, since your classes become tied to a specific AOP version.
- See the instrumentation chapter in the user guide for more information.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a561">
- <para>In POJO Cache 2.x release, do I still need
- <literal>annoc</literal>
- ?
- </para>
- </question>
-
- <answer>
- <para>No. POJO Cache 2.x requires JDK 5, and recommends load-time instrumentation. Alternatively the offline aopc tool may be used.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a57">
- <para>How do I use aopc on multiple module directories?</para>
- </question>
-
- <answer>
- <para>In aopc, you specify the src path for a specific directory. To
- pre-compile multiple ones, you will need to invoke aopc multiple
- times.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a57a">
- <para>Does POJO Cache provide a listener/event model for catching changes?</para>
- </question>
-
- <answer>
- <para>Yes. See the javadoc for PojoCache.addListener() and @PojoCacheListener.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a58">
- <para>What's in the
- <literal>pojocaches-aop.xml</literal>
- configuration?
- </para>
- </question>
-
- <answer>
- <para>
- These descriptors are necessary for instrumentation. However, you typically do not need to touch them since they include a rule
- which matches the classes with an @Replicable annotation. Therefore, all you need to do, is just
- annotate your class with @Replicable. Advanced users may decide to customize them with special AOP prepare statements that match
- classes which do not have @Replicable.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a58a">
- <para>What's the difference between
- <literal>jboss-aop.xml</literal>
- <literal>pojocache-aop.xml</literal>
- ?
- </para>
- </question>
-
- <answer>
- <para>
- <literal>pojocache-aop.xml</literal>
- is essentially a
- <literal>jboss-aop.xml</literal>
- ,
- except it is used specifically for POJO Cache. The analogy is similar to JBoss' own
- MBean service file
- <literal>jboss-service.xml</literal>
- , for example. So in our documentation,
- we will use these two terms interchangeably.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a59">
- <para>Can I use annotations instead of editing the AOP XML descriptors?</para>
- </question>
-
- <answer>
- <para>Yes, in release 2.0, we recommend you use the @Replicable annotation, and don't bother with editing the AOP files.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a60">
- <para>Is there a problem with using a custom AOP descriptor over the provided annotations?</para>
- </question>
-
- <answer>
- <para>The only real benefit to a custom AOP descriptor is if you can't easily add the annotation to the class source (it's not under your control).
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a61">
- <para>What are the
- <literal>@org.jboss.cache.pojo.annotation.Transient</literal>
- and
- <literal>@org.jboss.cache.pojo.annotation.Serializable</literal>
- field level annotations?
- </para>
- </question>
-
- <answer>
- <para>In 2.0, we also offer two additional field-level annotations. The first one,
- <literal>@org.jboss.cache.pojo.Transient</literal>
- ,
- when applied has the same effect as declaring a field
- <literal>transient</literal>
- . POJO Cache
- won't put this field under management.
- </para>
- <para>The second one,
- <literal>@org.jboss.cache.pojo.Serializable</literal>
- when applied,
- will cause POJO Cache to
- treat the field as a Serializable object even when it is
- <literal>@org.jboss.cache.pojo.Replicable</literal>
- .
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a62">
- <para>Why do you recommend load-time over compile-time instrumentation?</para>
- </question>
-
- <answer>
- <para> The major problem with compile-time instrumentation is that it adds a binary dependency on your class files to whatever
- version of JBoss AOP that was used to run aopc. Once this has been done, the class may not work with a future version of
- JBoss AOP (although the AOP team tries to ensure binary compatibility across minor revisions). Load-time doesn't have
- this problem since the class is instrumented only in memory, and only when it is loaded.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a63">
- <para>Is it possible to store the same object multiple times but
- with different Fqn paths? Like /foo/byName and /foo/byId ?
- </para>
- </question>
-
- <answer>
- <para>Yes, you can use POJO Cache to do that. It supports the
- notion of multiple object references. POJO Cache manages the unique object
- through association of the dynamic cache interceptor.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a64">
- <para>Do I have to instrument my objects?
- </para>
- </question>
-
- <answer>
- <para> You can also attach objects that implement
- <literal>Serializable</literal>. However, you lose field-level replication and object identity preservation.
- This is really only supported as a compatibility measure. It is definately worth useing instrumentation.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a65">
- <para>Will POJO Cache intercept changes made from Java Reflection?</para>
- </question>
-
- <answer>
- <para>Yes and No. Since POJO Cache intercepts field changes, any method
- of an object that has been annotated with @Replicable will be handled properly when called with reflection.
- However, modifying fields using reflection is not currently supported.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a66">
- <para>When I declare my POJO to be "aspectized", what happens to the
- fields with transient, static, and final modifiers?
- </para>
- </question>
-
- <answer>
- <para>POJO Cache currently will ignore the fields with these
- modifiers. That is, it won't put these fields into the cache (and
- thus no replication either).
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a67">
- <para>What are those keys such as
- <literal>JBoss:internal:class</literal>
- and
- <literal>PojoInstance</literal>
- ?
- </para>
- </question>
-
- <answer>
- <para>They are for internal use only. Users should ignore these keys
- and values in the node hashmap.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a68">
- <para>What about Collection classes? Do I need to declare them
- "prepared"?
- </para>
- </question>
-
- <answer>
- <para>No. Since the Collection classes such as
- <literal>ArrayList</literal>
- are java util classes, aop by default
- won't instrument these classes. Instead, POJO Cache will generate
- a dynamic class proxy for the Collection classes (upon the
- <literal>attach</literal>
- call is invoked). The proxy will
- delegate the operations to a cache interceptor that implements the
- actual Collection classes APIs. That is, the system classes won't be
- invoked when used in POJO Cache.
- </para>
-
- <para>Internally, the cache interceptor implements the APIs by
- direct interaction with respect to the underlying cache store. Note
- that this can have implications in performance for certain APIs. For
- example, both
- <literal>ArrayList</literal>
- and
- <literal>LinkedList</literal>
- will have the same implementation.
- Plan is currently underway to optimize these APIs.
- </para>

- <question id="a69">
- <para>How do I use
- <literal>List</literal>
- ,
- <literal>Set</literal>
- ,
- and
- <literal>Map</literal> with POJO Cache?
- </para>
- </question>
-
- <answer>
- <para>POJO Cache supports all classes that implement
- <literal>List</literal>
- ,
- <literal>Set</literal>
- , and
- <literal>Map</literal>
- without instrumentation. This is done using a dynamic proxy. Here is an example using
- <literal>ArrayList</literal>:
- </para>
-
- <programlisting role="JAVA"><![CDATA[
- ArrayList list = new ArrayList();
- list.add("first");
-
- cache.attach("/list/test", list); // Put the list under the cache
- list.add("second"); // Won't work since AOP intercepts the dynamic proxy not the original POJO.
-
- ArrayList myList = (List)cache.find("/list/test"); // we are getting a dynamic proxy instead
- myList.add("second"); // it works now
- myList.add("third");
- myList.remove("third");
- ]]></programlisting>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a70">
- <para>What is the proper way of assigning two different keys with
- Collection class object?
- </para>
- </question>
-
- <answer>
- <para>Let's say you want to assign a
- <literal>List</literal>
- object
- under two different names, you will need to use the class proxy to
- insert the second time to ensure both are managed by the cache. Here
- is the code snippet.
- </para>
-
- <programlisting role="JAVA"><![CDATA[
- ArrayList list = new ArrayList();
- list.add("first");
-
- cache.attach("/list", list); // Put the list under the aop cache
-
- ArrayList myList = (List)cache.find("/list"); // we are getting a dynamic proxy instead
- myList.add("second"); // it works now
-
- cache.attach("/list_alias", myList); // Note you will need to use the proxy here!!
- myList.remove("second");
- ]]></programlisting>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a71">
- <para>OK, so I know I am supposed to use proxy when manipulating the
- Collection classes once they are managed by the cache. But what
- happens to POJOs that share the Collection objects, e.g., a
- <literal>List</literal>
- instance that is shared by two objects??
- </para>
- </question>
-
- <answer>
- <para>POJOss that share Collection instance references will be
- handled by the cache automatically. That is, when you ask the Cache
- to manage it, the Cache will dynamically swap out the regular
- Collection references with the dynamic proxy ones. As a result, it
- is transparent to you.
- </para>
- </answer>
- </qandaentry>
-
- <qandaentry>
- <question id="a72">
- <para>What happens when my instrumented object contains collections?
- </para>
- </question>
-
- <answer>
- <para>When an object is passed to
- <literal>attach</literal>
- , it will recursively map the field
- members into the cache store as well. If the field member is of a
- Collection class (e.g., List, Set, or Map), POJO Cache will first
- map the collection into cache. Then, it will swap out
- the field reference with an corresponding proxy reference.
- </para>
-
- <para>This is necessary so that an internal update on the field
- member will be intercepted by the cache.
- </para>
- </answer>

-
-
- <qandaentry>
- <question id="a73">
- <para>What are the limitations of using Java Collections in POJO Cache?</para>
- </question>
- <answer>
- <para>
- List, Set, and Map are supported; however, these APIs do not stipulate
- of constraints like whether a null key or value is allowed. Therefore the behavior of an attached collection may differ
- slightly from the originals Java implementation. The behavior implemented by POJO Cache follows
- java.util.HashSet for any Set type, java.util.ArrayList for any List type, and java.util.HashMap for any Map type.s

- Core Cache. Passivation uses the combination of eviction and a cache loader such that when the
- items are old, it will be evicted from memory and store in a cache store (can be DB or file). Next time,
- when the item needs to be accessed again, we will retrieve it from the cache store.

+ <title>General Information</title>
+
+ <qandaentry>
+ <question id="a49">
+ <para>What is POJO Cache?</para>
+ </question>
+
+ <answer>
+ <para>POJO Cache is a fine-grained field-level replicated and
+ transactional POJO (plain old Java object) cache. By POJO, we mean
+ that the cache: 1) automatically manages object mapping and
+ relationship for a client under both local and replicated cache
+ mode, 2) provides support for inheritance relationship between
+ "aspectized" POJOs. By leveraging the dynamic AOP in JBossAop, it is
+ able to map a complex object into the cache store, preserve and
+ manage the object relationship behind the scene. During replication
+ mode, it performs fine-granularity (i.e., on a per-field basis)
+ update, and thus has the potential to boost cache performance and
+ minimize network traffic.
+ </para>
+
+ <para>From a user perspective, once your POJO is managed by the
+ cache, all cache operations are transparent. Therefore, all the
+ usual in-VM POJO method semantics are still preserved, providing
+ ease of use. For example, if a POJO has been put in POJO Cache (by
+ calling
+ <literal>attach</literal>
+ , for example), then any POJO get/set
+ method will be
+ intercepted by POJO Cache to provide the data from the
+ cache.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a1">
+ <para>What is the relationship between Core Cache and POJO Cache?</para>
+ </question>
+
+ <answer>
+ <para>Cores Cache is a traditional generic distributed cache system.
+ POJO Cache uses Core Cache as the underlying distributed state system to achieve object caching.
+ As a result, all the replication aspects are configured with the Cache configuration XML.
+ Additionally, POJO Cache also has API to expose the Cache interface (via
+ <literal>getCache()</literal>
+ API).
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a52">
+ <para>What is the difference between Core Cache and
+ POJO Cache?
+ </para>
+ </question>
+
+ <answer>
+ <para>Think of POJO Cache as a Cache on steroids. :-)
+ Seriously, both are cache stores-- one is a generic cache and the other other one POJO Cache.
+ However, while Cache only
+ provides pure object reference storage (e.g.,
+ <literal>put(FQN fqn,
+ Object key, Object value)
+ </literal>
+ ), POJO Cache goes beyond that
+ and performs fine-grained field level replication object mapping and
+ relationship management for a user behind the scenes. As a result,
+ if you have complex object systems that you would like to cache, you
+ can have POJO Cache manage it for you. You simply treat your
+ object systems as they are residing in-memory, e.g., use your
+ regular POJO methods without worrying about cache management.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a521">
+ <para>How does POJO Cache work then?</para>
+ </question>
+
+ <answer>
+ <para>POJO Cache uses the JBoss AOP project to perform field level
+ interception. This allows POJO Cache to monitor changes to your object model, and react
+ accordingly.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a522">
+ <para>What's changed between 1.x and 2.x release then?</para>
+ </question>
+
+ <answer>
+ <para>Starting in 2.0 release, we have a separate library for POJO Cache,
+ <literal>pojocache.jar</literal>
+ that
+ is extra to the core
+ <literal>jboss-cache.jar</literal>
+ . Since we uses Cache as a delegate, user
+ will need to have a regular xml to configure the core Cache functionality (e.g., replication and locking
+ aspect). In addition, there is also the
+ <literal>pojocache-aop.xml</literal>
+ that specifies the POJO Cache
+ interceptor stack (that can be left as default).
+ </para>
+ <para>Additionally, here are the changed features:
+ <itemizedlist>
+ <listitem>
+ <para>New APIs. It replaces
+ <literal>putObject, removeObject, and get</literal>
+ with
+ <literal>attach, detach, and find</literal>
+ .
+ </para>
+ </listitem>
+ <listitem>
+ <para>New POJO based events that a user can subscribe to.</para>
+ </listitem>
+ <listitem>
+ <para>New configuration pojocache-aop.xml specifically for POJO Cache, in addition to
+ the regular cache-service.xml for the delegating Cache.
+ </para>
+ </listitem>
+ <listitem>
+ <para>New package namespace (
+ <literal>org.jboss.cache.pojo)</literal>
+ for POJO Cache.
+ The previous
+ <literal>org.jboss.cache.aop</literal>
+ space has been deprecated.
+ </para>
+ </listitem>
+ </itemizedlist>
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a53">
+ <para>How do you use POJO Cache?</para>
+ </question>
+
+ <answer>
+ <para>In order to use POJO Cache, you will need to:</para>
+
+ <itemizedlist>
+ <listitem>
+ <para>Annotate your POJOt with @Replicable.
+ </para>
+ </listitem>
+ <listitem>
+ <para>Instrument your POJO. This can be done at load-time using special JVM arguments (prefered), or at compile time using the
+ AOP precompiler tool (aopc). See the user guide for more specific details on instrumentation.
+ </para>
+ </listitem>
+ </itemizedlist>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a541">
+ <para>What is the JDK version required to run POJO Cache 2.x?</para>
+ </question>
+
+ <answer>
+ <para>POJO Cache 2.x requires Java 5 or newer.</para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a542">
+ <para>Can I run POJO Cache as a standalone mode?</para>
+ </question>
+
+ <answer>
+ <para>Yes, same as the Core Cache library, you can run POJO Cache either as a standalone or
+ inside an application server.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a543">
+ <para>What is the JBoss AS recommended version to run POJO Cache 2.x?</para>
+ </question>
+
+ <answer>
+ <para>POJO Cache can be run either in AS4.0.5 (and up) and 5.0. But either way, it will require
+ JDK5.0 though.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a56">
+ <para>Can I pre-compile objects used in POJO Cache, so that I don't have to provide an AOP descriptor?
+ </para>
+ </question>
+
+ <answer>
+ <para>Yes. The AOP library included with POJO Cache has a pre-compiler called
+ <literal>aopc</literal> that can be used to instrument objects in advance. However,
+ this is not the recommended approach, since your classes become tied to a specific AOP version.
+ See the instrumentation chapter in the user guide for more information.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a561">
+ <para>In POJO Cache 2.x release, do I still need
+ <literal>annoc</literal>
+ ?
+ </para>
+ </question>
+
+ <answer>
+ <para>No. POJO Cache 2.x requires JDK 5, and recommends load-time instrumentation. Alternatively the offline aopc tool may be used.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a57">
+ <para>How do I use aopc on multiple module directories?</para>
+ </question>
+
+ <answer>
+ <para>In aopc, you specify the src path for a specific directory. To
+ pre-compile multiple ones, you will need to invoke aopc multiple
+ times.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a57a">
+ <para>Does POJO Cache provide a listener/event model for catching changes?</para>
+ </question>
+
+ <answer>
+ <para>Yes. See the javadoc for PojoCache.addListener() and @PojoCacheListener.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a58">
+ <para>What's in the
+ <literal>pojocaches-aop.xml</literal>
+ configuration?
+ </para>
+ </question>
+
+ <answer>
+ <para>
+ These descriptors are necessary for instrumentation. However, you typically do not need to touch them since they include a rule
+ which matches the classes with an @Replicable annotation. Therefore, all you need to do, is just
+ annotate your class with @Replicable. Advanced users may decide to customize them with special AOP prepare statements that match
+ classes which do not have @Replicable.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a58a">
+ <para>What's the difference between
+ <literal>jboss-aop.xml</literal>
+ <literal>pojocache-aop.xml</literal>
+ ?
+ </para>
+ </question>
+
+ <answer>
+ <para>
+ <literal>pojocache-aop.xml</literal>
+ is essentially a
+ <literal>jboss-aop.xml</literal>
+ ,
+ except it is used specifically for POJO Cache. The analogy is similar to JBoss' own
+ MBean service file
+ <literal>jboss-service.xml</literal>
+ , for example. So in our documentation,
+ we will use these two terms interchangeably.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a59">
+ <para>Can I use annotations instead of editing the AOP XML descriptors?</para>
+ </question>
+
+ <answer>
+ <para>Yes, in release 2.0, we recommend you use the @Replicable annotation, and don't bother with editing the AOP files.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a60">
+ <para>Is there a problem with using a custom AOP descriptor over the provided annotations?</para>
+ </question>
+
+ <answer>
+ <para>The only real benefit to a custom AOP descriptor is if you can't easily add the annotation to the class source (it's not under your control).
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a61">
+ <para>What are the
+ <literal>@org.jboss.cache.pojo.annotation.Transient</literal>
+ and
+ <literal>@org.jboss.cache.pojo.annotation.Serializable</literal>
+ field level annotations?
+ </para>
+ </question>
+
+ <answer>
+ <para>In 2.0, we also offer two additional field-level annotations. The first one,
+ <literal>@org.jboss.cache.pojo.Transient</literal>
+ ,
+ when applied has the same effect as declaring a field
+ <literal>transient</literal>
+ . POJO Cache
+ won't put this field under management.
+ </para>
+ <para>The second one,
+ <literal>@org.jboss.cache.pojo.Serializable</literal>
+ when applied,
+ will cause POJO Cache to
+ treat the field as a Serializable object even when it is
+ <literal>@org.jboss.cache.pojo.Replicable</literal>
+ .
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a62">
+ <para>Why do you recommend load-time over compile-time instrumentation?</para>
+ </question>
+
+ <answer>
+ <para> The major problem with compile-time instrumentation is that it adds a binary dependency on your class files to whatever
+ version of JBoss AOP that was used to run aopc. Once this has been done, the class may not work with a future version of
+ JBoss AOP (although the AOP team tries to ensure binary compatibility across minor revisions). Load-time doesn't have
+ this problem since the class is instrumented only in memory, and only when it is loaded.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a63">
+ <para>Is it possible to store the same object multiple times but
+ with different Fqn paths? Like /foo/byName and /foo/byId ?
+ </para>
+ </question>
+
+ <answer>
+ <para>Yes, you can use POJO Cache to do that. It supports the
+ notion of multiple object references. POJO Cache manages the unique object
+ through association of the dynamic cache interceptor.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a64">
+ <para>Do I have to instrument my objects?
+ </para>
+ </question>
+
+ <answer>
+ <para> You can also attach objects that implement
+ <literal>Serializable</literal>. However, you lose field-level replication and object identity preservation.
+ This is really only supported as a compatibility measure. It is definately worth useing instrumentation.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a65">
+ <para>Will POJO Cache intercept changes made from Java Reflection?</para>
+ </question>
+
+ <answer>
+ <para>Yes and No. Since POJO Cache intercepts field changes, any method
+ of an object that has been annotated with @Replicable will be handled properly when called with reflection.
+ However, modifying fields using reflection is not currently supported.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a66">
+ <para>When I declare my POJO to be "aspectized", what happens to the
+ fields with transient, static, and final modifiers?
+ </para>
+ </question>
+
+ <answer>
+ <para>POJO Cache currently will ignore the fields with these
+ modifiers. That is, it won't put these fields into the cache (and
+ thus no replication either).
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a67">
+ <para>What are those keys such as
+ <literal>JBoss:internal:class</literal>
+ and
+ <literal>PojoInstance</literal>
+ ?
+ </para>
+ </question>
+
+ <answer>
+ <para>They are for internal use only. Users should ignore these keys
+ and values in the node hashmap.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a68">
+ <para>What about Collection classes? Do I need to declare them
+ "prepared"?
+ </para>
+ </question>
+
+ <answer>
+ <para>No. Since the Collection classes such as
+ <literal>ArrayList</literal>
+ are java util classes, aop by default
+ won't instrument these classes. Instead, POJO Cache will generate
+ a dynamic class proxy for the Collection classes (upon the
+ <literal>attach</literal>
+ call is invoked). The proxy will
+ delegate the operations to a cache interceptor that implements the
+ actual Collection classes APIs. That is, the system classes won't be
+ invoked when used in POJO Cache.
+ </para>
+
+ <para>Internally, the cache interceptor implements the APIs by
+ direct interaction with respect to the underlying cache store. Note
+ that this can have implications in performance for certain APIs. For
+ example, both
+ <literal>ArrayList</literal>
+ and
+ <literal>LinkedList</literal>
+ will have the same implementation.
+ Plan is currently underway to optimize these APIs.
+ </para>
+ </answer>

+ <question id="a69">
+ <para>How do I use
+ <literal>List</literal>
+ ,
+ <literal>Set</literal>
+ ,
+ and
+ <literal>Map</literal> with POJO Cache?
+ </para>
+ </question>
+
+ <answer>
+ <para>POJO Cache supports all classes that implement
+ <literal>List</literal>
+ ,
+ <literal>Set</literal>
+ , and
+ <literal>Map</literal>
+ without instrumentation. This is done using a dynamic proxy. Here is an example using
+ <literal>ArrayList</literal>:
+ </para>
+
+ <programlisting role="JAVA"><![CDATA[
+ ArrayList list = new ArrayList();
+ list.add("first");
+
+ cache.attach("/list/test", list); // Put the list under the cache
+ list.add("second"); // Won't work since AOP intercepts the dynamic proxy not the original POJO.
+
+ ArrayList myList = (List)cache.find("/list/test"); // we are getting a dynamic proxy instead
+ myList.add("second"); // it works now
+ myList.add("third");
+ myList.remove("third");
+ ]]></programlisting>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a70">
+ <para>What is the proper way of assigning two different keys with
+ Collection class object?
+ </para>
+ </question>
+
+ <answer>
+ <para>Let's say you want to assign a
+ <literal>List</literal>
+ object
+ under two different names, you will need to use the class proxy to
+ insert the second time to ensure both are managed by the cache. Here
+ is the code snippet.
+ </para>
+
+ <programlisting role="JAVA"><![CDATA[
+ ArrayList list = new ArrayList();
+ list.add("first");
+
+ cache.attach("/list", list); // Put the list under the aop cache
+
+ ArrayList myList = (List)cache.find("/list"); // we are getting a dynamic proxy instead
+ myList.add("second"); // it works now
+
+ cache.attach("/list_alias", myList); // Note you will need to use the proxy here!!
+ myList.remove("second");
+ ]]></programlisting>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a71">
+ <para>OK, so I know I am supposed to use proxy when manipulating the
+ Collection classes once they are managed by the cache. But what
+ happens to POJOs that share the Collection objects, e.g., a
+ <literal>List</literal>
+ instance that is shared by two objects??
+ </para>
+ </question>
+
+ <answer>
+ <para>POJOss that share Collection instance references will be
+ handled by the cache automatically. That is, when you ask the Cache
+ to manage it, the Cache will dynamically swap out the regular
+ Collection references with the dynamic proxy ones. As a result, it
+ is transparent to you.
+ </para>
+ </answer>
+ </qandaentry>
+
+ <qandaentry>
+ <question id="a72">
+ <para>What happens when my instrumented object contains collections?
+ </para>
+ </question>
+
+ <answer>
+ <para>When an object is passed to
+ <literal>attach</literal>
+ , it will recursively map the field
+ members into the cache store as well. If the field member is of a
+ Collection class (e.g., List, Set, or Map), POJO Cache will first
+ map the collection into cache. Then, it will swap out
+ the field reference with an corresponding proxy reference.
+ </para>
+
+ <para>This is necessary so that an internal update on the field
+ member will be intercepted by the cache.
+ </para>
+ </answer>
+ </qandaentry>
+
+
+ <qandaentry>
+ <question id="a73">
+ <para>What are the limitations of using Java Collections in POJO Cache?</para>
+ </question>
+ <answer>
+ <para>
+ List, Set, and Map are supported; however, these APIs do not stipulate
+ of constraints like whether a null key or value is allowed. Therefore the behavior of an attached collection may differ
+ slightly from the originals Java implementation. The behavior implemented by POJO Cache follows
+ java.util.HashSet for any Set type, java.util.ArrayList for any List type, and java.util.HashMap for any Map type.s

- <title>Running The Demo GUI</title>
-
- <para>
- The demo is run by calling the ant script (via the driver) with the
- <literal>run.demo</literal>
- target. E.g.,
- </para>
-
- <para>
- <literal>ant run.demo</literal>
- </para>
- <para>
- This will cause a GUI window to appear, giving you a tree view of the cache in the top pane and a BeanShell
- view of the JVM in the lower pane.
- </para>
- <para>
- The BeanShell view is preset with the following variables:
- <itemizedlist>
- <listitem>
- <literal>cache</literal>
- - a reference to the POJO Cache interface, used by the GUI instance.
- </listitem>
- <listitem>
- <literal>transactionManager</literal>
- - a reference to the registered transaction manager.
- </listitem>
- </itemizedlist>
- The references made available to the BeanShell window point to the same cache instance used by the tree view in
- the GUI above.
- </para>
-
- <para>
- To run the demo as a replicated demo, it is useful to start another command line window and run the ant script
- again as you did above. Now you will have two cache instances running in two separate GUIs, replicating state
- to each other.
- </para>
-
- </section>
-
- <section>
- <title>Tutorials</title>
- It is recommended that you shut down and restart the demo GUI for each of the following tutorials, to ensure
- clean caches every time. To inspect POJO attribute changes via GUI, please refer to the POJO Cache
- <ulink

+ <para>
+ POJO Cache is an in-memory, transactional, and clustered cache system that
+ allows users to operate on a POJO (Plain Old Java Object) transparently and without
+ active user management of either replication or persistence aspects.
+
+ JBoss Cache, which includes POJO Cache, is a 100% Java based library that can be
+ run either as a standalone program or inside an application server.
+ </para>
+
+ <para>
+ This document is meant to be a user and reference guide to explain the architecture, api, configuration, and
+ examples for POJO Cache. We assume the readers are familiar with both JGroups and the core JBoss Cache usages.
