OpenLayers Cluster Recalculate

Question

So, I have a number of items clustered in OpenLayers.

I\'m using a strategy that clusters the items based on their attributes.

I change an item\'s attribute.

Answer 1

OpenLayers.Strategy.Cluster.cluster method recalculate only if it is a zoomechanged event or clusters object does not exist. remove the clusters object and call cluster on Cluster object.

var clustering=new OpenLayers.Strategy.Cluster()
var vectorlayer = new OpenLayers.Layer.Vector('Vectorlayer', {
                                              strategies: [clustering]
});

//ADD_LOTS_OF_FEATURES_TO_VECTOR_LAYER

clustering.distance=value;
//cluster() recalculate only if it is a zoomechanged event or clusters object does not exist.
clustering.clusters = null; //remove cluster object so that it calculates again.
clustering.cluster();
