org.oscim.layers

Class MapEventLayer

java.lang.Object

org.oscim.layers.Layer

org.oscim.layers.MapEventLayer

All Implemented Interfaces:

EventListener, GestureListener, Map.InputListener

public class MapEventLayer
extends Layer
implements Map.InputListener, GestureListener

Changes Viewport by handling move, fling, scale, rotation and tilt gestures.

TODO rewrite using gesture primitives to build more complex gestures: maybe something similar to this https://github.com/ucbvislab/Proton
