Detailed Description

depth first iterator through a vtkGraph

vtkTreeDFSIterator performs a depth first search traversal of a tree.

First, you must set the tree on which you are going to iterate, and then optionally set the starting vertex and mode. The mode is either DISCOVER (default), in which case vertices are visited as they are first reached, or FINISH, in which case vertices are visited when they are done, i.e. all adjacent vertices have been discovered already.

After setting up the iterator, the normal mode of operation is to set up a while(iter->HasNext()) loop, with the statement vtkIdType vertex = iter->Next() inside the loop.

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.

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 vtkTreeDFSIterator::SetMode ( int  mode)

Set the visit mode of the iterator.

Mode can be DISCOVER (0): Order by discovery time FINISH (1): Order by finish time Default is DISCOVER. Use DISCOVER for top-down algorithms where parents need to be processed before children. Use FINISH for bottom-up algorithms where children need to be processed before parents.

virtual int vtkTreeDFSIterator::GetMode ( )

Set the visit mode of the iterator.

Mode can be DISCOVER (0): Order by discovery time FINISH (1): Order by finish time Default is DISCOVER. Use DISCOVER for top-down algorithms where parents need to be processed before children. Use FINISH for bottom-up algorithms where children need to be processed before parents.
