Detailed Description

Iterates through all incoming edges to a vertex.

vtkInEdgeIterator iterates through all edges whose target is a particular vertex. Instantiate this class directly and call Initialize() to traverse the vertex of a graph. Alternately, use GetInEdges() on the graph to initialize the iterator. it->Next() returns a vtkInEdgeType structure, which contains Id, the edge's id, and Source, the edge's source vertex.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ Initialize()

void vtkInEdgeIterator::Initialize ( vtkGraph g,
vtkIdType  v 
)

Initialize the iterator with a graph and vertex.

◆ GetGraph()

virtual vtkGraph* vtkInEdgeIterator::GetGraph ( )

Get the graph and vertex associated with this iterator.

◆ GetVertex()

◆ Next()

vtkInEdgeType vtkInEdgeIterator::Next ( )
inline

Returns the next edge in the graph.

Definition at line 69 of file vtkInEdgeIterator.h.

◆ NextGraphEdge()

vtkGraphEdge* vtkInEdgeIterator::NextGraphEdge ( )

Just like Next(), but returns heavy-weight vtkGraphEdge object instead of the vtkEdgeType struct, for use with wrappers.

The graph edge is owned by this iterator, and changes after each call to NextGraphEdge().

◆ HasNext()

bool vtkInEdgeIterator::HasNext ( )
inline

Whether this iterator has more edges.
