Examples of org.apache.cayenne.graph.GraphEvent

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); 
```
