slash.navigation.mapview.mapsforge.updater.UpdateDecoupler

extends Object

Decouples position list changes from the map updating: serializes the work onto a single background thread and dispatches it to the EventMapUpdater for the list's current characteristics. Keeps the event listeners off the rendering work.
