Class BlockConstraintSolver

java.lang.Object

org.metacsp.framework.ConstraintSolver

org.metacsp.framework.multi.MultiConstraintSolver

org.metacsp.multi.spatial.blockAlgebra.BlockConstraintSolver

All Implemented Interfaces:

java.io.Serializable

public class BlockConstraintSolver
extends MultiConstraintSolver

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