java.lang.Object

org.metacsp.framework.ConstraintSolver

org.metacsp.framework.multi.MultiConstraintSolver

org.metacsp.multi.spatial.rectangleAlgebra.RectangleConstraintSolver

All Implemented Interfaces:

java.io.Serializable

public class RectangleConstraintSolver
extends MultiConstraintSolver

This class represents Rectangle constraints. Each constraint represents two dimension Allen relations between spatial entities. In rectangle Algebra, each spatial entity is restricted to be an axis parallel rectangle.
