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 ); ... 
```


        readInitialFactHandle( context, 
                               _session.getRuleData() );
        
        for ( ProtobufMessages.EntryPoint _ep : _session.getRuleData().getEntryPointList() ) {
            WorkingMemoryEntryPoint wmep = context.wm.getEntryPoints().get( _ep.getEntryPointId() );
            readFactHandles( context,
                             _ep,
                             ((NamedEntryPoint) wmep).getObjectStore() );
        }
