|

|
|
* @brief 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 <code>while(iter->HasNext())</code> loop, with the statement
|
||
|
|
* <code>vtkIdType vertex = iter->Next()</code> inside the loop.
|
||
|

* Thanks to David Doria for submitting this class.
