ClusterMapObject class abstract

Runtime snapshot of a visible icon cluster on the location view. Created and updated by ClusterMapObjectController. Member IconMapObject instances are hidden while grouped; the cluster marker is shown instead. Note: Position and membership are managed by the controller and cannot be changed through this interface. Use ClusterMapObjectListener (onClusterChanged) to refresh a custom cluster bitmap when the member count changes.
