Representation of a single graph edge.
Definition: vtkGraphEdge.h:40
Base class for graph data types.
Definition: vtkGraph.h:339
Iterates through all incoming edges to a vertex.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual void SetGraph(vtkGraph *graph)
Protected method for setting the graph used by Initialize().
vtkInEdgeType Next()
Returns the next edge in the graph.
void Initialize(vtkGraph *g, vtkIdType v)
Initialize the iterator with a graph and vertex.
static vtkInEdgeIterator * New()
bool HasNext()
Whether this iterator has more edges.
const vtkInEdgeType * End
vtkGraphEdge * NextGraphEdge()
Just like Next(), but returns heavy-weight vtkGraphEdge object instead of the vtkEdgeType struct,...
vtkGraphEdge * GraphEdge
~vtkInEdgeIterator() override
const vtkInEdgeType * Current
a simple class to control print indentation
