|
|
* @brief A directed graph.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* vtkDirectedGraph is a collection of vertices along with a collection of
|
||
|
|
* directed edges (edges that have a source and target). ShallowCopy()
|
||
|
|
* and DeepCopy() (and CheckedShallowCopy(), CheckedDeepCopy())
|
||
|
|
* accept instances of vtkTree and vtkMutableDirectedGraph.
|
||
|
|
*
|
||
|
|
* vtkDirectedGraph is read-only. To create an undirected graph,
|
||
|
|
* use an instance of vtkMutableDirectedGraph, then you may set the
|
||
|
|
* structure to a vtkDirectedGraph using ShallowCopy().
