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 interfaceTraversalListener<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 interfaceTraversalListener<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 interfaceTraversalListener<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 interfaceTraversalListener<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 interfaceTraversalListener<V,E>
- Parameters:
e
- the vertex traversal event.- See Also:
TraversalListener.vertexFinished(VertexTraversalEvent)
