Method Detail

guaranteesDistinct

public boolean guaranteesDistinct()

Description copied from interface: InnerQuadConstraintStream

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

Returns:

true if the guarantee of distinct tuples is provided
