Interface Constraint

All Known Implementing Classes:

DiffNotEqualConstraint, NotEqualConstraint

public interface Constraint

A constraint specifies the allowable combinations of values for a set of variables. Each constraint consists of a pair , where scope is a tuple of variables that participate in the constraint and rel is a relation that defines the values that those variables can take on.

Note: Implementations of this interface define the different kinds of relations that constraints can represent.
