[rules-users] drrols type declaration and how are the equals and hashcode for those types implemented...

[Edson Tirelli]

   Yap.

   This was one of the latest pieces of code I've been working on. Basically
Drools continues to support property setting in conf files, system
properties, and directly through the setProperty() method on
KnowledgeBaseConfiguration. What I added was type-safe configuration through
the Options API:

http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-compiler/src/test/java/org/drools/conf/KnowledgeBaseConfigurationTest.java

    Quick example:

        KnowledgeBaseConfiguration kbconf =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
        kbconf.setOption( AssertBehaviorOption.EQUALITY );
        KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase( kbconf
);

    Feedback and help documenting, more than welcome... ;)
