Interface Tuple<T extends TupleImpl>

All Superinterfaces:
BaseTuple, DoubleLinkedEntry<TupleImpl>, Serializable, SingleLinkedEntry<TupleImpl>
All Known Implementing Classes:
EvalNodeLeftTuple, LeftTuple, NotNodeLeftTuple, ReactiveFromNodeLeftTuple, RightTuple, RuleTerminalNodeLeftTuple, SubnetworkTuple, TupleImpl, WindowTuple
public interface Tuple<T extends TupleImpl> extends BaseTuple, Serializable, DoubleLinkedEntry<TupleImpl>
Partial matches are propagated through the Rete network as Tuples. Each Tuple Is able to return the FactHandleImpl members of the partial match for the requested pattern. The pattern refers to the index position of the FactHandleImpl in the underlying implementation.

  • Method Details

    • toObjects

      default Object[] toObjects()
      Specified by:
      toObjects in interface BaseTuple

    • setFactHandle

      void setFactHandle(FactHandle handle)

    • getOriginalFactHandle

      InternalFactHandle getOriginalFactHandle()

    • getSubTuple

      T getSubTuple(int elements)
      Returns the ReteTuple that contains the "elements" first elements in this tuple.

      Use carefully as no cloning is made during this process.

      This method is used by TupleStartEqualsConstraint when joining a subnetwork tuple into the main network tuple;

      Parameters:
      elements - the number of elements to return, starting from the begining of the tuple
      Returns:
      a ReteTuple containing the "elements" first elements of this tuple or null if "elements" is greater than size;
