/**

* @class vtkOutEdgeIterator
|
|
* @brief Iterates through all outgoing edges from a vertex.
|
|
*
|
|
*
|
|
* vtkOutEdgeIterator iterates through all edges whose source is a particular
|
|
* vertex. Instantiate this class directly and call Initialize() to traverse
|
|
* the vertex of a graph. Alternately, use GetInEdges() on the graph to
|
|
* initialize the iterator. it->Next() returns a vtkOutEdgeType structure,
|
|
* which contains Id, the edge's id, and Target, the edge's target vertex.
