Detailed Description

Iterates through all outgoing edges from a vertex.

vtkOutEdgeIterator iterates through all edges whose source 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 vtkOutEdgeType structure, which contains Id, the edge's id, and Target, the edge's target vertex.

Member Function Documentation

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

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

Reimplemented from vtkObject.

virtual const char* vtkOutEdgeIterator::GetClassName ( ) [virtual]

Reimplemented from vtkObject.

static int vtkOutEdgeIterator::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkOutEdgeIterator::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkOutEdgeIterator* vtkOutEdgeIterator::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkObject.

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

Initialize the iterator with a graph and vertex.

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

Get the graph and vertex associated with this iterator.

virtual vtkIdType vtkOutEdgeIterator::GetVertex ( ) [virtual]

Get the graph and vertex associated with this iterator.

vtkOutEdgeType vtkOutEdgeIterator::Next ( ) [inline]

Returns the next edge in the graph.

Definition at line 65 of file vtkOutEdgeIterator.h.

vtkGraphEdge* vtkOutEdgeIterator::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 vtkOutEdgeIterator::HasNext ( ) [inline]

Whether this iterator has more edges.

Definition at line 82 of file vtkOutEdgeIterator.h.

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

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