Detailed Description

Iterates through all incoming edges to a vertex.

vtkInEdgeIterator iterates through all edges whose target 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 vtkInEdgeType structure, which contains Id, the edge's id, and Source, the edge's source vertex.

Just like Next(), but returns heavy-weight vtkGraphEdge object instead of the vtkEdgeType struct, for use with wrappers.

The graph edge is owned by this iterator, and changes after each call to NextGraphEdge().
