PointerStack( x, y, width, height )

Implements: None

The PointerStack is used to create a list of PointerInterfaces that will be traversed in descending order to ensure only the top-most element is called. Thus, interfaces that are added later will be "above" those that were added earlier. In the given example, the second simple mouse pointer would be called rather than the first where the two overlap.

pointer = new PointerStack( 0, 0, room_width, room_height )

pointer.add( new PointerSimpleMouse( new ShapeRectangle( 10, 10, 20, 20 ) );
pointer.add( new PointerSimpleMouse( new ShapeRectangle( 20, 20, 20, 20 ) );

update( _x, _y )

Returns: N/A undefined

Name	Type	Purpose
_x	undef	none provided
_y	undef	none provided

Calls for this PointerInterface to be updated, will check all instances and update the top-most interface that it finds. Any previous interactions will have their exit code called as well.

remove( interface )

Returns: N/A undefined

Name	Type	Purpose
interface	mixed	A PointerInterface or PointerStack.

Removes the specified interface from the stack.

---

add( interface )

Returns: N/A undefined

Name	Type	Purpose
interface	mixed	A PointerInterface or PointerStack.

Adds the specified interface to the stack.

---

draw( _x, _y, _color )

Returns: N/A undefined

Name	Type	Purpose
_x	undef	none provided
_y	undef	none provided
_color	undef	none provided

---

is( type )

Returns: boolean (true or false)

Name	Type	Purpose
type	Constructor	The Constructor to compare this against.

Returns true if the provided type is PointerStack.
