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 ); ... 
```

        StockTickInterface tick8 = new StockTick( 8,
                "DROO",
                50,
                System.currentTimeMillis() );


        WorkingMemoryEntryPoint entry = session.getWorkingMemoryEntryPoint( "stream1" );


        InternalFactHandle handle5 = (InternalFactHandle) entry.insert( tick5 );
        InternalFactHandle handle6 = (InternalFactHandle) entry.insert( tick6 );
        InternalFactHandle handle7 = (InternalFactHandle) entry.insert( tick7 );
        InternalFactHandle handle8 = (InternalFactHandle) entry.insert( tick8 );


        assertNotNull( handle5 );
        assertNotNull( handle6 );
        assertNotNull( handle7 );
        assertNotNull( handle8 );


        assertTrue( handle5.isEvent() );
        assertTrue( handle6.isEvent() );
        assertTrue( handle7.isEvent() );
        assertTrue( handle8.isEvent() );


        session.fireAllRules();


        System.out.println(results);
        assertEquals( 2,
                results.size() );
        assertEquals( 30,
                ( (Number) results.get( 0 ) ).intValue() );
        assertEquals( 110,
                ( (Number) results.get( 1 ) ).intValue() );


        // the 3 non-matched facts continue to exist in the entry point
        assertEquals(3,
                entry.getObjects().size());
        // but no fact was inserted into the main session
        assertEquals(0,
                session.getObjects().size());
