Class TupleMatch

java.lang.Object
  org.drools.util.AbstractBaseLinkedListNode
      org.drools.reteoo.TupleMatch

All Implemented Interfaces:

java.io.Serializable, LinkedListNode

---

public class TupleMatch
extends AbstractBaseLinkedListNode

TupleMatch maintains a reference to the parent ReteTuple and a List of all resulting joins. This is a List rather than a single instance reference because we need to create a join for each TupleSink branches. A reference is also maintained to the ObjectMatches instance; this is so the FactHandleImpl that is used in the join can be referenced, and also any other TupleMatches the FactHandleImpl is joined with.

java.util.List	getJoinedTuples()           Return the List of joined ReteTuples.
ObjectMatches	getObjectMatches()           Returns the referenced ObjectMatches which provides the FactHandleImpl the ReteTuple is joined with.
ReteTuple	getTuple()           Return the parent ReteTuple
