#include <rw/bintree.h>
RWBinaryTree bt;
RWBinaryTreeConstIterator iterate(bt);


Provides a const iterator for class RWBinaryTree. Traverses the tree from the "smallest" to "largest" element, where "smallest" and "largest" are defined by the virtual function compareTo(). Note that this approach is generally less efficient than using the member function RWBinaryTree::apply().

Like all Rogue Wave iterators, the "current item" is undefined immediately after construction -- you must define it by using operator() or some other (valid) operation.

Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it brings undefined results.
