org.jboss.cache.Caches, which allows for users to access a Cache using various collection interfaces
----------------------------------------------------------------------------------------------------
Key: JBCACHE-941
URL: http://jira.jboss.com/jira/browse/JBCACHE-941
Project: JBoss Cache
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Reporter: Elias Ross
Assigned To: Manik Surtani
The java.util.Collections utility class supplies useful methods for dealing with legacy interfaces and wrapping collection classes for concurrency, type safety, read-only, etc.
In a simiilar vein, I wrote a "Caches" class that returns java.util.Map instances for a Node, which allow data to be modified through the standard Map interface.
This I expect to be extremely useful for allowing uses to integrate their existing application with JBoss Cache, and will eliminate some of the confusion of using a new API and they can use the API they know best. Users also often demand an API which is "generic" so that their code is not tied to a particular vendor.
There are basically two methods in Caches, one looks like this:
Cache cache = DefaultCacheFactory.getInstance().createCache();
Map m = Caches.asMap(cache);
m.put("foo", "bar");
The API and examples explain themselves.
"Caches" could also include other useful methods for printing or reporting.
Note that this functionality could be considered duplicated from PojoCache...)

Add a Node.clearChildren() functionality
----------------------------------------

For next major API change.
Equivalent to Node.clearData(), but removes the children.
Use case is trying to atomically remove everything under some structural node, while leaving the structural node in place. The best that can be done now is either:
1) Remove the node and re-add it, but this doesn't work for remote caches with INVALIDATION, since both the removal and the addition propagate as invalidation messages. Remote caches are left w/o the structural node. Plus it's not atomic.
2) Query for the children and remove them one by one. Also not atomic, plus if lockParentForChildInsertRemove is false you have to deal with other threads possibly adding new children while you are removing.

TreeCache usage should not depend on trove.jar
----------------------------------------------
Key: JBCACHE-877
URL: http://jira.jboss.com/jira/browse/JBCACHE-877
Project: JBoss Cache
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 1.4.0.SP1
Reporter: Galder Zamarreno
Assigned To: Manik Surtani
Priority: Minor
A customer is upgrading from JBC 1.1 to 1.4.0.SP1 and
even though it only uses plain TreeCache, it gets a
NoClassDefFoundError for trove classes.
2006-11-23 13:19:03,781 ERROR RpcDispatcher exception=java.lang.NoClassDefFoundError: gnu/trove/TObjectHashingStrategy
This is a TreeCacheAop/PojoCache dependency and therefore,
should be isolated and attempted to be loaded only when
PojoCache used.
