Detailed Description

breadth first search iterator through a vtkTree

vtkTreeBFSIterator performs a breadth first search traversal of a tree.

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.

Reimplemented from vtkTreeIterator.

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.
