Method Detail

transpose

public GraphType transpose(GraphType orig,
                           GraphToolkit<GraphType,EdgeType,VertexType> toolkit)

Transpose a graph. Note that the original graph is not modified; the new graph and its vertices and edges are new objects.

Parameters:

orig - the graph to transpose

toolkit - a GraphToolkit to be used to create the transposed Graph

Returns:

the transposed Graph

getTransposedGraphVertex

public VertexType getTransposedGraphVertex(VertexType v)

Get the vertex in the transposed graph which corresponds to the given vertex in the original graph.

Parameters:

v - the vertex in the original graph

Returns:

the equivalent vertex in the transposed graph

getOriginalGraphVertex

public VertexType getOriginalGraphVertex(VertexType v)

Get the vertex in the original graph which corresponds to the given vertex in the transposed graph.

Parameters:

v - the vertex in the transposed graph

Returns:

the equivalent vertex in the original graph
