Representation of a single graph edge.
Definition: vtkGraphEdge.h:40
Base class for graph data types.
Definition: vtkGraph.h:288
a simple class to control print indentation
Definition: vtkIndent.h:40
abstract base class for most VTK objects
Definition: vtkObject.h:60
Iterates through all outgoing edges from a vertex.
vtkGraphEdge * NextGraphEdge()
Just like Next(), but returns heavy-weight vtkGraphEdge object instead of the vtkEdgeType struct,...
static vtkOutEdgeIterator * New()
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
bool HasNext()
Whether this iterator has more edges.
~vtkOutEdgeIterator() override
vtkOutEdgeType Next()
Returns the next edge in the graph.
void Initialize(vtkGraph *g, vtkIdType v)
Initialize the iterator with a graph and vertex.
int vtkIdType
Definition: vtkType.h:287
