protected Class Franson.Map.GMapGraphicsOverlay - extends GMap.GOverlay

implements the GMap.GOverlay interface. Connects ontop of google as a google overlay and maintains state of a map-type agnostic map-surface layer.
All our other graphics and layers then use this (instance) (via getSurface).
In practice this should only be instantiated from within the Franson.GMapAdapter.

Constructor

Parameters:
mapSurface <Franson.Map.MapSurface>

Properties

_dirty - private object

_events - private object

_map - private object

_mapSurface - private object
