Iterates through all edges in a graph.
vtkGraphEdge * GraphEdge
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
const vtkOutEdgeType * Current
virtual void SetGraph(vtkGraph *graph)
bool HasNext()
Whether this iterator has more edges.
~vtkEdgeListIterator() override
const vtkOutEdgeType * End
vtkGraphEdge * NextGraphEdge()
Just like Next(), but returns heavy-weight vtkGraphEdge object instead of the vtkEdgeType struct,...
static vtkEdgeListIterator * New()
vtkEdgeType Next()
Returns the next edge in the graph.
Representation of a single graph edge.
