Class RightInputAdapterNode

java.lang.Object
  org.drools.common.BaseNode
      org.drools.reteoo.ObjectSource
          org.drools.reteoo.RightInputAdapterNode

All Implemented Interfaces:

Externalizable, Serializable, NetworkNode, NodeMemory, LeftTupleSink, LeftTupleSinkNode, Sink

public class RightInputAdapterNode
extends ObjectSource
implements LeftTupleSinkNode, NodeMemory

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.
