// .NAME vtkOutEdgeIterator - Iterates through all outgoing edges from a vertex.
//
// .SECTION Description
// 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.
//
// .SECTION See Also
// vtkGraph vtkInEdgeIterator
