Method Summary
 void connectedComponentFinished(ConnectedComponentTraversalEvent e)
          Called to inform listeners that the traversal of the current connected component has finished.
 void connectedComponentStarted(ConnectedComponentTraversalEvent e)
          Called to inform listeners that a traversal of a new connected component has started.
 void edgeTraversed(EdgeTraversalEvent e)
          Called to inform the listener that the specified edge have been visited during the graph traversal.
 void vertexTraversed(VertexTraversalEvent e)
          Called to inform the listener that the specified vertex have been visited during the graph traversal.
 

Method Detail

connectedComponentFinished

void connectedComponentFinished(ConnectedComponentTraversalEvent e)
Called to inform listeners that the traversal of the current connected component has finished.

Parameters:
e - the traversal event.

connectedComponentStarted

void connectedComponentStarted(ConnectedComponentTraversalEvent e)
Called to inform listeners that a traversal of a new connected component has started.

Parameters:
e - the traversal event.

edgeTraversed

void edgeTraversed(EdgeTraversalEvent e)
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.

Parameters:
e - the edge traversal event.

vertexTraversed

void vertexTraversed(VertexTraversalEvent e)
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.

Parameters:
e - the vertex traversal event.
