Groups IconMapObject instances into clusters depending on zoom and proximity. Referenced from LocationWindow. Register icons with addIconMapObject, then optionally customize cluster appearance in ClusterMapObjectControllerListener (onClusterCreated) and ClusterMapObjectListener (onClusterChanged).

getClusters() → List<ClusterMapObject>
Returns a snapshot of currently visible clusters.
getRadius() → double
Returns cluster radius in density-independent pixels.
isEnabled() → bool
