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

getLeftHandSide

public BiLeftHandSide<A,B> getLeftHandSide()

Specified by:

getLeftHandSide in class DroolsAbstractBiConstraintStream<Solution_,A,B>

toString

public String toString()

Overrides:

toString in class Object
