Package org.apache.jena.graph

Class GraphListenerBase

java.lang.Object

org.apache.jena.graph.GraphListenerBase

All Implemented Interfaces:

GraphListener

public abstract class GraphListenerBase
extends Object
implements GraphListener

A GraphListener that converts "add" and "delete" operations to addEvent(org.apache.jena.graph.Triple) and deleteEvent(org.apache.jena.graph.Triple) together with optional startRead() and finishRead().

Method Details

notifyAddTriple

public void notifyAddTriple(Graph g,
 Triple t)

Description copied from interface: GraphListener

Method called when a single triple has been added to the graph.

Specified by:

notifyAddTriple in interface GraphListener

notifyAddArray

public void notifyAddArray(Graph g,
 Triple[] triples)

Description copied from interface: GraphListener

Method called when an array of triples has been added to the graph.

Specified by:

notifyAddArray in interface GraphListener

notifyAddList

public void notifyAddList(Graph g,
 List<Triple> triples)

Description copied from interface: GraphListener

Method called when a list [of triples] has been added to the graph.

Specified by:

notifyAddList in interface GraphListener

notifyAddIterator

public void notifyAddIterator(Graph g,
 Iterator<Triple> it)

Description copied from interface: GraphListener

Method called when an iterator [of triples] has been added to the graph

Specified by:

notifyAddIterator in interface GraphListener

notifyAddGraph

public void notifyAddGraph(Graph g,
 Graph added)

Description copied from interface: GraphListener

Method called when another graph g has been used to specify the triples added to our attached graph.

Specified by:

notifyAddGraph in interface GraphListener

Parameters:

g - the graph of triples added

notifyDeleteTriple

public void notifyDeleteTriple(Graph g,
 Triple t)

Description copied from interface: GraphListener

Method called when a single triple has been deleted from the graph.

Specified by:

notifyDeleteTriple in interface GraphListener

notifyDeleteList

public void notifyDeleteList(Graph g,
 List<Triple> triples)

Description copied from interface: GraphListener

Method called when a list [of triples] has been deleted from the graph.

Specified by:

notifyDeleteList in interface GraphListener

notifyDeleteArray

public void notifyDeleteArray(Graph g,
 Triple[] triples)

Description copied from interface: GraphListener

Method called when an array of triples has been deleted from the graph.

Specified by:

notifyDeleteArray in interface GraphListener

notifyDeleteIterator

public void notifyDeleteIterator(Graph g,
 Iterator<Triple> it)

Description copied from interface: GraphListener

Method called when an iterator [of triples] has been deleted from the graph.

Specified by:

notifyDeleteIterator in interface GraphListener

notifyDeleteGraph

public void notifyDeleteGraph(Graph g,
 Graph removed)

Description copied from interface: GraphListener

Method to call when another graph has been used to specify the triples deleted from our attached graph.

Specified by:

notifyDeleteGraph in interface GraphListener

Parameters:

g - the graph of triples added

notifyEvent

public void notifyEvent(Graph source,
 Object value)

Description copied from interface: GraphListener

method to call for a general event. value is usually a GraphEvents. Special attention is drawn to GraphEvents.removeAll and events whose GraphEvents.getTitle() is "remove" (see GraphEvents.remove(Node, Node, Node). Unlike other notifications, the listener cannot tell which triples have been modified, since they have already been deleted by the time this event is sent, and the event does not include a record of them.

Specified by:

notifyEvent in interface GraphListener
