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 ); ... 
```

        this.outIdentifier = outIdentifier;
    }


    public Collection execute(Context context) {
        StatefulKnowledgeSession ksession = ((KnowledgeCommandContext) context).getStatefulKnowledgesession();
        WorkingMemoryEntryPoint ep = ksession.getWorkingMemoryEntryPoint(entryPoint);


        Collection col = null;


        if ( filter != null ) {


            col =  ep.getObjects( this.filter );
        } else {
            col =  ep.getObjects( );
        }


        if ( this.outIdentifier != null ) {
            List objects = new ArrayList( col );

        WorkingMemoryEntryPoint ep = ksession.getWorkingMemoryEntryPoint(entryPoint);
        Object object = ep.getObject( factHandle );
        
        if (this.outIdentifier != null) {
            ((StatefulKnowledgeSessionImpl)ksession).session.getExecutionResult()
                .getResults().put( this.outIdentifier, object );
