Class RightInputAdapterNode

java.lang.Object

org.drools.core.common.BaseNode

org.drools.core.reteoo.ObjectSource

org.drools.core.reteoo.RightInputAdapterNode

All Implemented Interfaces:

Externalizable, Serializable, MemoryFactory<RightInputAdapterNode.RiaNodeMemory>, NetworkNode, LeftTupleNode, LeftTupleSink, LeftTupleSinkNode, PathEndNode, Sink

public class RightInputAdapterNode
extends ObjectSource
implements LeftTupleSinkNode, PathEndNode, MemoryFactory<RightInputAdapterNode.RiaNodeMemory>

When joining a subnetwork into the main network again, RightInputAdapterNode adapts the subnetwork's tuple into a fact in order right join it with the tuple being propagated in the main network.
