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.

Member Function Documentation

static vtkInEdgeIterator* vtkInEdgeIterator::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

static int vtkInEdgeIterator::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkObject.

virtual int vtkInEdgeIterator::IsA ( const char * name ) [virtual]

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 vtkObject.

static vtkInEdgeIterator* vtkInEdgeIterator::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkObject.

virtual vtkObjectBase* vtkInEdgeIterator::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkObject.

vtkInEdgeIterator* vtkInEdgeIterator::NewInstance ( ) const

Reimplemented from vtkObject.

void vtkInEdgeIterator::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

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.

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

Initialize the iterator with a graph and vertex.

virtual vtkGraph* vtkInEdgeIterator::GetGraph ( ) [virtual]

Get the graph and vertex associated with this iterator.

virtual vtkIdType vtkInEdgeIterator::GetVertex ( ) [virtual]

Get the graph and vertex associated with this iterator.

vtkInEdgeType vtkInEdgeIterator::Next ( ) [inline]

Returns the next edge in the graph.

Definition at line 66 of file vtkInEdgeIterator.h.

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().

bool vtkInEdgeIterator::HasNext ( ) [inline]

Whether this iterator has more edges.

Definition at line 83 of file vtkInEdgeIterator.h.

virtual void vtkInEdgeIterator::SetGraph ( vtkGraph * graph ) [protected, virtual]

Protected method for setting the graph used by Initialize().
