org.drools.reteoo.RightInputAdapterNode
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. @author Mark Proctor @author Bob McWhirter @author Edson Tirelli
