Public Class GraphEvent

An event which indicates that a graph structure change occurred. This low-level event is generated by a graph when its structure changes. The event is passed to every IGraphListener object that registered to receive such events using the graph's addGraphListener method.

The object that implements the GraphListener interface gets this GraphEvent when the event occurs.

Each GraphEvent has a type that signals what kind of change occurred in the graph and a data object that is the object (either node or edge) that was involved in the structural change of the graph, e.g., the node that has been created or the edge that has been reversed.
