Examples of GraphListener

com.hp.hpl.jena.graph.GraphListener
Interface for listening to graph-level update events. Each time the graph is poked to add or remove some triples, and after that poke has completed without throwing an exception, all the listeners attached to the Graph are informed about the poke.
The notifications are, in general, given before further changes to the graph are made. Listeners are discouraged from making further modifications to the same graph since that will invalidate this property for other listeners.

Some modifications may result in multiple notifications in some cases. For example, a bulk notification with {@link #notifyAddArray(Graph,Triple[])}, may, or may not, be accompanied by several {@link #notifyAddTriple(Graph,Triple)}notifications, one for each triple. If possible, Graph implementations should avoid such duplicate notifications and only give the bulk notifications, see {@link com.hp.hpl.jena.graph.impl.GraphWithPerform}. When these duplicate notifications occur, each should happen immediately after the change it signifies is complete. Thus, in the previous example, if the array has two triples, the pattern is:
1. The first triple is added.
2. {@link #notifyAddTriple(Graph,Triple)} for the first triple.
3. The second triple is added.
4. {@link #notifyAddTriple(Graph,Triple)} for the second triple.
5. {@link #notifyAddArray(Graph,Triple[])} for the array.
To track all changes to a graph it is necessary to consider all the methods in this interface, including {@link #notifyEvent(Graph,Object)}.
com.sun.sgs.impl.service.nodemap.affinity.graph.GraphListener
A listener which detects object uses by Identities within tasks and builds a graph based on that information.
diva.graph.GraphListener
A listener for changes in a graph's structure or contents, which are communicated through GraphEvent objects. GraphListeners register themselves with a GraphModel object, and receive events from Nodes and Edges contained by that model's root graph or any of its subgraphs. @author Michael Shilman @author John Reekie @version $Id: GraphListener.java,v 1.11 2005/07/08 19:55:01 cxh Exp $ @Pt.AcceptedRating Yellow
nz.ac.waikato.modeljunit.GraphListener
This ModelListener builds a graph of the observed parts of the model. Note that it is some other class (typically a Tester subclass) that determines which parts of the model are explored. As well as building the graph, this listener also keeps track of which paths have not yet been explored. Internally, it keeps track of two bitsets for each node/state. The 'done_' set records the outgoing transitions that have been taken/explored since the last call to clearDoneTodo(). The 'wasEnabled_' set records the actions that have been observed to have true guards at some point since the last call to clearDoneTodo() (this includes implicitly true guards, where the action has no explicit guard).
org.apache.clerezza.rdf.core.event.GraphListener
A class that is interested in graph events implements this interface and is then added as listener to a ListenableTripleCollection or one of its subclasses. When the ListenableTripleCollection is modified, then the GraphListener is notified. @author mir
