public interface Positionable

A common interface for objects that can be positioned with an x and y coordinate

Method Summary

Modifier and Type	Method and Description
<T extends Positionable> void	addPostionChangeListener(PositionChangeListener<T> listener) Adds a PositionChangeListener to be notified of coordinate changes
float	getDistanceTo(Positionable positionable) Returns this distance between this object's x,y coordinates and the provided Positionable's xy coordinates
float	getX() Returns the x coordinate of this object
float	getY() Returns the y coordinate of this object
<T extends Positionable> void	removePositionChangeListener(PositionChangeListener<T> listener) Removes a PositionChangeListener to stop it being notified of coordinate changes

Method Detail

getX

float getX()

Returns the x coordinate of this object

Returns:

0 by default

getY

float getY()

Returns the y coordinate of this object

Returns:

0 by default

getDistanceTo

float getDistanceTo(Positionable positionable)

Returns this distance between this object's x,y coordinates and the provided Positionable's xy coordinates

Parameters:

positionable - The Positionable to retrieve the distance from

Returns:

0 if the xy coordinates are the same

addPostionChangeListener

<T extends Positionable> void addPostionChangeListener(PositionChangeListener<T> listener)

Adds a PositionChangeListener to be notified of coordinate changes

Parameters:

listener - The PositionChangeListener to add

removePositionChangeListener

<T extends Positionable> void removePositionChangeListener(PositionChangeListener<T> listener)

Removes a PositionChangeListener to stop it being notified of coordinate changes

Parameters:

listener - The PositionChangeListener to remove
