Examples of org.drools.runtime.rule.WorkingMemoryEntryPoint

org.drools.runtime.rule.WorkingMemoryEntryPoint
An entry-point is an abstract channel through where facts are inserted into the engine.

Drools 5 supports multiple entry-points into a single StatefulKnowledgeBase: the default, anonymous entry-point, as well as as many user declared entry points the application requires.

To get a reference to an entry point, just request the session:
```
 StatefulKnowledgeSession session = kbase.newStatelessKnowledgeSession(); ... WorkingMemoryEntryPoint entrypoint = session.getWorkingMemoryEntryPoint("my entry point"); 
```
Once a reference to an entry point is acquired, the application can insert, update and retract facts to/from that entry-point as usual:
```
 ... FactHandle factHandle = entrypoint.insert( fact ); ... entrypoint.update( factHandle, newFact ); ... entrypoint.retract( factHandle ); ... 
```

        KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();


        kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() );


        final StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
        final WorkingMemoryEntryPoint ep = ksession.getWorkingMemoryEntryPoint( "testep" );


        List list = new ArrayList();
        ksession.setGlobal( "list",
                            list );


        list.add( new Person( "darth" ) );
        ep.insert( new Cheese( "cheddar" ) );


        ksession.fireAllRules();
        assertEquals( 3,
                      list.size() );
    }
