Fetching all the children of a picked node or link

[arashkav]

When we get the object from a FlowmapLayerPickingInfo object, we can not see all the building blocks of the picked object at the highest granularity.

I can see the children but those children themselves might have other children. Is there any function that wen can call and gives us all the nodes that creating a clustered node or the origins/destination of a clustered link?

Yes, I think what you are looking for is ClusterIndex.expandCluster()

You should be able to get access to the clusterIndex in a click/hover listener by calling flowmapLayer.state?.dataProvider.getSelectors().getClusterIndex().
