Deprecated.

@Deprecated
public abstract static class Tree.TreeDropCriterion
extends ServerSideCriterion

Lazy loading accept criterion for Tree. Accepted target nodes are loaded from server once per drag and drop operation. Developer must override one method that decides accepted tree nodes for the whole Tree.

Initially pretty much no data is sent to client. On first required criterion check (per drag request) the client side data structure is initialized from server and no subsequent requests requests are needed during that drag and drop operation.
