supercluster 2.2.0

A port of MapBox's javascript supercluster library for fast clustering, with added mutable clustering support.

2.2.0

• FEATURE: Add replacePoints method which allows the index's points to be replaced with the original ones when a supercluster index is created in a separate isolate.
• BUGFIX: Fix highestZoom/lowestZoom values when inserting in a mutable supercluster causes a new cluster to form.

2.1.1

• BUGFIX: SuperclusterMutable now removes existing points when calling load(). This was the documented behaviour but there was a bug in the implementation. Thanks @Robbendebiene for pointing this out.

2.1.0

• Add new contains function which returns true if the provided point is contained in the index.

2.0.0

• BREAKING: SuperclusterImmutable no longer has a points argument. Instead the points should be set by calling load() as is done with SuperclusterMutable.
• BREAKING: onClusterDataChange callback has been removed. If you want to react to cluster data changes you can do so after:
  • load is called. - remove is called and returns true. - modifyPointData is called and returns true.

1.0.0

• BREAKING: ClusterOrMapPoint has been renamed to LayerElement
• BREAKING: Cluster has been renamed to LayerCluster
• BREAKING: MapPoint has been renamed to LayerPoint
• BREAKING: Supercluster now no longer supports points with a null x or y. The getX and getY functions are now non-nullable. If you have points with null x/y you should filter them out.
• Introduced SuperclusterMutable which allows adding/removing points. This uses a rbush instead of kdbush as the point index which is slower but supports mutation. If you don't need mutation you should stick with the normal Supercluster.

0.1.0

• Add the ability to aggregate map point data in clusters.

0.0.2

• Export Cluster, MapPoint and ClusterOrMapPoint

0.0.1+1

• Fix code example in README

0.0.1

• Initial version.
