diva.graph.GraphEvent
A graph event that is emitted when anything interesting happens inside a graph by way of a GraphModel. The source of a graph event is the object which caused the change to the graph model, such as a particular controller of the graph or a user algorithm.
Each graph event contains an ID and a previous value for all changes and deletions, the specifics of which are described on a case-by-case basis below. @see GraphModel @author Michael Shilman @author John Reekie @version $Id: GraphEvent.java,v 1.16 2005/07/08 19:55:01 cxh Exp $ @Pt.AcceptedRating Yellow
org.apache.cayenne.graph.GraphEvent
An event indicating a change in the object graph. A change is expressed as a GraphDiff, so the easiest way to process the event is the following:
```
 GraphChangeHandler handler = ..; event.getDiff().apply(handler); 
```

org.apache.clerezza.rdf.core.event.GraphEvent
This class represent a modification event that occured on a TripleCollection. A GraphEvent object keeps information about this event. These information are: The Triple that was part of the modification, the type of modification (addition or removal) and the TripleCollection that was modified. @author mir

org.gephi.graph.api.GraphEvent

Graph event interface, that {@link GraphListener} receives when the graph ismodified. Each event is specific to a particular view, which can be get from the getSource() method.

- ADD_NODES:	Add nodes to the graph
- REMOVE_NODES:	Remove nodes from the graph, with their edges
- ADD_EDGES:	Add edges to the graph
- REMOVE_EDGES:	Remove edges from the graph
- MOVE_NODE:	Move nodes on the hierarchy, parent node is changed
- VISIBLE_VIEW:	Current visible view is changed
- NEW_VIEW:	A new view is created
- DESTROY_VIEW:	A view is destroyed
- EXPAND:	Expand nodes in the hierarchy
- RETRACT:	Retract nodes in the hierarchy
- META_EDGES_UPDATE	Meta-Edges are updated
