All Implemented Interfaces:

java.io.Serializable

public class GraphPoolEvent
extends DragosEvent

A GraphPoolEvent is triggered for graph pool related actions such as opening, closing, or deleting a graph pool. The source of this event is the DataSourceURL, not the GraphPool, because GraphPool is not Serializable.
