Detailed Description

Iterates through all edges in a graph.

vtkEdgeListIterator iterates through all the edges in a graph, by traversing the adjacency list for each vertex. You may instantiate this class directly and call SetGraph() to traverse a certain graph. You may also call the graph's GetEdges() method to set up the iterator for a certain graph.

Note that this class does NOT guarantee that the edges will be processed in order of their ids (i.e. it will not necessarily return edge 0, then edge 1, etc.).

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.

◆ Next()

vtkEdgeType vtkEdgeListIterator::Next ( )

Returns the next edge in the graph.

◆ NextGraphEdge()

vtkGraphEdge* vtkEdgeListIterator::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 vtkEdgeListIterator::HasNext ( )

Whether this iterator has more edges.
