Iterates through adjacent vertices in a graph.
~vtkAdjacentVertexIterator() override
vtkIdType Next()
Returns the next edge in the graph.
bool HasNext()
Whether this iterator has more edges.
virtual void SetGraph(vtkGraph *graph)
Protected method for setting the graph used by Initialize().
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void Initialize(vtkGraph *g, vtkIdType v)
Initialize the iterator with a graph and vertex.
static vtkAdjacentVertexIterator * New()
Representation of a single graph edge.
