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.

Specified by:

guaranteesDistinct in interface InnerBiConstraintStream<Solution_,A>

Returns:

true if the guarantee of distinct tuples is provided
