org.jacop.constraints.DisjointConditional

public class DisjointConditional
extends Diff

DisjointConditional constraint assures that any two rectangles from a vector of rectangles does not overlap in at least one direction. The execption from this rule is specified on the list of tuple [recti, rectj, C], where recti and rectj are integers representing given rectangles positions on the list of rectangles (starting from 1) and C is FDV 0..1. When C=1 then rectnagles must not overlap otherwise the overlaping is not checked.
