Constructor Detail

BavetGroupBiConstraintStream

public BavetGroupBiConstraintStream(BavetConstraintFactory<Solution_> constraintFactory,

Method Detail

guaranteesDistinct

public boolean guaranteesDistinct()

Description copied from interface: InnerBiConstraintStream

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

Returns:

true if the guarantee of distinct tuples is provided

getFromStreamList

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

Specified by:
