  • Field Details

    • dim

      final int dim

    • length

      public final IntVar[] length
      It specifies the length of the rectangle in each dimension.

    • origin

      public final IntVar[] origin
      It specifies the origin of the rectangle in each dimension.

  • Constructor Details

    • Rectangle

      public Rectangle(IntVar[] origin, IntVar[] length)
      It constructs a rectangle.
      Parameters:
      origin - the origin of the rectangle in each dimension.
      length - the length of the rectangle in each dimension.

    • Rectangle

      public Rectangle(IntVar[] list)
      It constructs a rectangle.
      Parameters:
      list - it specifies for each dimension (one after the other) its origin and length.

    • Rectangle

      public Rectangle(List<? extends IntVar> list)
      It constructs a rectangle.
      Parameters:
      list - it specifies for each dimension (one after the other) its origin and length.

    • Rectangle

      public Rectangle(Rectangle rect)
      It constructs a rectangle.
      Parameters:
      rect - the rectangle based on which a new rectangle is created.

  • Method Details

    • dim

      int dim()

    • domOverlap

      public boolean domOverlap(Rectangle r)
      It returns true if this rectangle overlaps with a given rectangle.
      Parameters:
      r - the rectangle for which the overlapping is being checked.
