void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkOutEdgeType Next()
Returns the next edge in the graph.
Representation of a single graph edge.

bool HasNext()
Whether this iterator has more edges.
const vtkOutEdgeType * Current
Base class for graph data types.
Definition: vtkGraph.h:287
a simple class to control print indentation
Definition: vtkIndent.h:39
const vtkOutEdgeType * End
Iterates through all outgoing edges from a vertex.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on...
