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 ); ... 
```

            readRightTuples( initialFactHandle,
                             context );
        }
        while ( context.readShort() == PersisterEnums.ENTRY_POINT) {
            String entryPointId = context.stream.readUTF();
            WorkingMemoryEntryPoint wmep = context.wm.getEntryPoints().get( entryPointId );
            readFactHandles( context,
                             ( (NamedEntryPoint) wmep ).getObjectStore() );
        }
        InternalFactHandle handle = context.wm.getInitialFactHandle();
        while (context.stream.readShort() == PersisterEnums.LEFT_TUPLE) {
