org.drools.core.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.

             LeftTupleSource lts;
             LeftTupleSource startRianLts = null;
             if ( NodeTypeEnums.isTerminalNode(pmem.getNetworkNode())) {
                 lts = ((TerminalNode)pmem.getNetworkNode()).getLeftTupleSource();
             } else {
                 RightInputAdapterNode rian = (RightInputAdapterNode)pmem.getNetworkNode();
                 startRianLts = rian.getStartTupleSource();
                 lts = rian.getLeftTupleSource();
             }
             AbstractTerminalNode.initPathMemory(pmem, lts, startRianLts, wm, removingRule); // re-initialise the PathMemory
         }
