[JBoss JIRA] Created: (JBRULES-1908) updated Drools docs content from SOA 4.2.CP03 Rules Guide

by Darrin Mison (JIRA)

updated Drools docs content from SOA 4.2.CP03 Rules Guide --------------------------------------------------------- Key: JBRULES-1908 URL: https://jira.jboss.org/jira/browse/JBRULES-1908 Project: JBoss Drools Issue Type: Task Security Level: Public (Everyone can see) Components: drools-docs-expert Reporter: Darrin Mison Assignee: Mark Proctor I revised the language of the "Insertion" section while fixing a couple of reported grammatical errors for the 4.2.CP03 SOA Rules Guide. The original language is the same in: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/soa_tags/4.3.0.FP01_B... , so these changes would also apply to the most recent docs. Updated content below, the section ids are different but you get the idea ;-) <section id="sect-JBoss_Rules_Reference_Manual-WorkingMemory_and_StatefulStateless_Sessions-Insertion"> <title>Insertion</title> <para> <firstterm>Insertion</firstterm> is the act of telling the WorkingMemory about the facts. </para> <important> <para> In many Expert Systems the term used for this concept is <firstterm>assert</firstterm> or <firstterm>assertion</firstterm>. However as the keyword <methodname>assert</methodname> is already used in many languages, Drools uses the keyword & term <methodname>insert</methodname>. You will often encounter these terms used interchangably in discussion of Rules Engines. </para> </important> <para> When inserted, the rule is examined for matches against the rules. The work of determining what rules to fire is done during insertion, but no rules are executed at this time. The rules are executed when <methodname>fireAllRules()</methodname> is called, and it should only be called after you have inserted all your facts. </para> <para> It is a common misconception that rule matching occurs when <methodname>fireAllRules()</methodname> is called. </para> <para> When an Object is inserted it returns a FactHandle. This FactHandle is the token used to represent your inserted Object inside the WorkingMemory, it is also how you will interact with the Working Memory when you wish to retract or modify an object. </para> <programlisting language="java">Cheese stilton = new Cheese("stilton"); FactHandle stiltonHandle = session.insert( stilton );</programlisting> <para> As mentioned in <xref linkend="sect-JBoss_Rules_Reference_Manual-The_Drools_Rule_Engine-RuleBase" /> a Working Memory can operate in two assertions modes: <firstterm>equality</firstterm> and <firstterm>identity</firstterm>. Identity is the default mode. The assertion mode determines how the Working Memory stores the facts and how it compares the newly inserted fact to previously inserted ones. If the Working Memory determines the fact to "be the same" as an already inserted one it will ignore the new fact and return the FactHandle for the previously inserted one. </para> <variablelist> <varlistentry> <term>Identity</term> <listitem> <para> Identity Mode uses an <classname>IdentityHashMap</classname>to store all asserted Objects. New facts being inserted are compared to existing facts "by reference". A new FactHandle will be returned if the object being inserted is not a reference to an object that has been inserted previously. </para> </listitem> </varlistentry> <varlistentry> <term>Equality</term> <listitem> <para> Equality Mode uses a <classname>HashMap</classname> to store all asserted Objects. New facts being inserted are compared to existing facts "by value". A new FactHandle will be returned if the content of the object is not identical to that of a previously inserted object. </para> </listitem> </varlistentry> </variablelist> </section> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBCL-84) Extend the ClassLoadingMetaData filtered package semantics

by Adrian Brock (JIRA)

Extend the ClassLoadingMetaData filtered package semantics ---------------------------------------------------------- Key: JBCL-84 URL: https://jira.jboss.org/jira/browse/JBCL-84 Project: JBoss ClassLoader Issue Type: Feature Request Components: MetaData Reporter: Adrian Brock Currently the ClassLoadingMetaData has some includedPackages and excludedPackages metadata. This is just a comma seperated list of explicit package names. This metadata should be extended to make it more flexible. e.g. using globing <classloader> <excluded type="glob">com.foo.*</included> or explicitly naming the filter <classloader> <excluded class="com.foo.MyClassFilter>...</excluded> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-2049) org.drools.runtime.rule StatefulRuleSession.fireAllRules(org.drools.runtime.rule.AgendaFilter af) has no AgendaFilter implementations

org.drools.runtime.rule StatefulRuleSession.fireAllRules(org.drools.runtime.rule.AgendaFilter af) has no AgendaFilter implementations ------------------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-2049 URL: https://jira.jboss.org/jira/browse/JBRULES-2049 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: drools-api, drools-core Affects Versions: 5.0.0.CR1 Environment: Java 1.5 Reporter: Bob Shanahan Assignee: Mark Proctor StatefulSession.fireAllRules(org.drools.spi.AgendaFilter af) has several implementations of AgendaFilter for filtering rules. Why aren't the AgendaFilters common? Even the Activation class between them is different, so it is not simple to workaround by wrapping org.drools.spi.AgendaFilter impls. It would be handy if there were out-of-the-box AgendaFilters for implementations of StatefulRuleSession. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1232) [solver] Selector refactor: configurable subset selections, topList usage etc

by Geoffrey De Smet (JIRA)

[solver] Selector refactor: configurable subset selections, topList usage etc ----------------------------------------------------------------------------- Key: JBRULES-1232 URL: http://jira.jboss.com/jira/browse/JBRULES-1232 Project: JBoss Rules Issue Type: Task Security Level: Public (Everyone can see) Components: Solver Reporter: Geoffrey De Smet Assigned To: Geoffrey De Smet Currently all moves are evaluated at every step (with a MaxAllForager at least) if you use the basic cached move factory selector. This doesn't scale well, especially for big data problems where in the beginning, just about every moves improves. The neighbourhood size (= amount of selected moves) could for example increase block-wise or timeGradient-wise until an improving solution is found. Notice the difference with the usage of FirstImprovingForager. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1457) please support containment test for map keys

by Godmar Back (JIRA)

please support containment test for map keys -------------------------------------------- Key: JBRULES-1457 URL: http://jira.jboss.com/jira/browse/JBRULES-1457 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Drl Parser/Builder Affects Versions: 4.0.4 Environment: any Reporter: Godmar Back Using MVEL as the language for clauses, there is no way to test whether a map's key contain a value. For instance: rule "number 1" when e : S(map.keySet() contains "x") then System.out.println("rule number 1"); end leads to a syntax error because Drool's parser does not allow function calls ("keySet())" in clauses. On the other hand, MVEL (according to Mike Brocks, please read http://jira.codehaus.org/browse/MVEL-53 ) does not provide an operator to test containment in a map's set (or values). He said he's considering adding a shortcut such as .keys and .values in 2.0 and recommended I open a Drools JIRA issue. Please provide a way to test for membership in a map's key and value set. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
