Method Detail

guaranteesDistinct

public boolean guaranteesDistinct()

Description copied from interface: InnerTriConstraintStream

This method will return true if the constraint stream is guaranteed to only produce distinct tuples. See InnerTriConstraintStream.distinct() for details.

Specified by:

guaranteesDistinct in interface InnerTriConstraintStream<Solution_,A,B>

Returns:

true if the guarantee of distinct tuples is provided

getFromStreamList

public List<BavetFromUniConstraintStream<Solution_,Object>> getFromStreamList()

Specified by:

getFromStreamList in class BavetAbstractConstraintStream<Solution_>

createNodeChain

public BavetJoinTriNode<A,B,C> createNodeChain(BavetNodeBuildPolicy<Solution_> buildPolicy,
                                                           Score<?> constraintWeight,
