|
|
*
|
|
*
|
|
* vtkMutableDirectedGraph is a directed graph which has additional methods
|
|
* for adding edges and vertices. AddChild() is a convenience method for
|
|
* constructing trees. ShallowCopy(), DeepCopy(), CheckedShallowCopy() and
|
|
* CheckedDeepCopy() will succeed for instances of vtkDirectedGraph,
|
|
* vtkMutableDirectedGraph and vtkTree.
