Description copied from interface: RectangleImmutable

Returns the union of this rectangle and the given rectangle.

Specified by:

union in interface RectangleImmutable

union

public final RectangleImmutable union(int rx1,
                       int ry1,
                       int rx2,

union

public final Rectangle union(List<RectangleImmutable> rectangles)

Calculates the union of the given rectangles, stores it in this instance and returns this instance.

Parameters:

rectangles - given list of rectangles

Returns:

this instance holding the union of given rectangles.

intersection

public final RectangleImmutable intersection(RectangleImmutable r)

Description copied from interface: RectangleImmutable

Returns the intersection of this rectangleand the given rectangle.

Specified by:

intersection in interface RectangleImmutable

intersection

public final RectangleImmutable intersection(int rx1,
                              int ry1,
                              int rx2,
