Method Details

connectedComponentFinished

public void connectedComponentFinished(ConnectedComponentTraversalEvent e)

Description copied from interface: TraversalListener

Called to inform listeners that the traversal of the current connected component has finished.

Specified by:

connectedComponentFinished in interface TraversalListener<V,E>

Parameters:

e - the traversal event.

See Also:

TraversalListener.connectedComponentFinished(ConnectedComponentTraversalEvent)

connectedComponentStarted

public void connectedComponentStarted(ConnectedComponentTraversalEvent e)

Description copied from interface: TraversalListener

Called to inform listeners that a traversal of a new connected component has started.

Specified by:

connectedComponentStarted in interface TraversalListener<V,E>

Parameters:

e - the traversal event.

See Also:

TraversalListener.connectedComponentStarted(ConnectedComponentTraversalEvent)

edgeTraversed

public void edgeTraversed(EdgeTraversalEvent<E> e)

Description copied from interface: TraversalListener

Called to inform the listener that the specified edge have been visited during the graph traversal. Depending on the traversal algorithm, edge might be visited more than once.

Specified by:

edgeTraversed in interface TraversalListener<V,E>

Parameters:

e - the edge traversal event.

See Also:

TraversalListener.edgeTraversed(EdgeTraversalEvent)

vertexTraversed

public void vertexTraversed(VertexTraversalEvent<V> e)

Description copied from interface: TraversalListener

Called to inform the listener that the specified vertex have been visited during the graph traversal. Depending on the traversal algorithm, vertex might be visited more than once.

Specified by:

vertexTraversed in interface TraversalListener<V,E>

Parameters:

e - the vertex traversal event.

See Also:

TraversalListener.vertexTraversed(VertexTraversalEvent)

vertexFinished

public void vertexFinished(VertexTraversalEvent<V> e)

Description copied from interface: TraversalListener

Called to inform the listener that the specified vertex have been finished during the graph traversal. Exact meaning of "finish" is algorithm-dependent; e.g. for DFS, it means that all vertices reachable via the vertex have been visited as well.

Specified by:

vertexFinished in interface TraversalListener<V,E>

Parameters:

e - the vertex traversal event.

TraversalListener.vertexFinished(VertexTraversalEvent)
