NonHierarchicalViewBasedAlgorithm

open class NonHierarchicalViewBasedAlgorithm<T : ClusterItem?> : NonHierarchicalDistanceBasedAlgorithm<T> , ScreenBasedAlgorithm<T>

Algorithm that can be used for managing large numbers of items (>1000 markers). This algorithm works the same way as NonHierarchicalDistanceBasedAlgorithm but works, only in visible area. It requires shouldReclusterOnMapMovement to be true in order to re-render clustering when camera movement changes the visible area.

Parameters

<T>

The ClusterItem type

Constructors

NonHierarchicalViewBasedAlgorithm

constructor(screenWidth: Int, screenHeight: Int)
