impose
public void impose(Store store)
Description copied from class:Constraint
It imposes the constraint in a given store.- Overrides:
impose
in classConstraint
- Parameters:
store
- the constraint store to which the constraint is imposed to.
-
narrowRectangles
void narrowRectangles(java.util.Set<IntVar> fdvQueue)
- Overrides:
narrowRectangles
in classDiff
-
findRectangles
private boolean findRectangles(Rectangle r, int index, java.util.List<IntRectangle> UsedRect, java.util.List<Rectangle> ProfileCandidates, java.util.List<Rectangle> OverlappingRects, java.util.Set<IntVar> fdvQueue)
-
profileNarrowing
void profileNarrowing(int i, Rectangle r, java.util.List<Rectangle> ProfileCandidates)
- Overrides:
profileNarrowing
in classDiff
-
satisfied
public boolean satisfied()
Description copied from interface:SatisfiedPresent
It checks if the constraint is satisfied. It can return false even if constraint is satisfied but not all variables in its scope are grounded. It needs to return true if all variables in its scope are grounded and constraint is satisfied.Implementations of this interface for constraints that are not PrimitiveConstraint may require constraint imposition and consistency check as a requirement to work correctly.
- Specified by:
satisfied
in interfaceSatisfiedPresent
- Overrides:
satisfied
in classDiff
- Returns:
- true if constraint is possible to verify that it is satisfied.
-
toString
public java.lang.String toString()
Description copied from class:Constraint
It produces a string representation of a constraint state.
