//===-- Support/iterator - "Portable" wrapper around <iterator> -*- C++ -*-===//
|
|
//
|
|
// This file provides a wrapper around the mysterious <iterator> header file.
|
|
// In GCC 2.95.3, the file defines a bidirectional_iterator class (and other
|
|
// friends), instead of the standard iterator class. In GCC 3.1, the
|
|
// bidirectional_iterator class got moved out and the new, standards compliant,
|
|
// iterator<> class was added. Because there is nothing that we can do to get
|
|
// correct behavior on both compilers, we have this header with #ifdef's. Gross
|
|
// huh?
|
|
//
|
|
// By #includ'ing this file, you get the contents of <iterator> plus the
|
|
// following classes in the global namespace:
|
|
//
|
|
// 1. bidirectional_iterator
|
|
// 2. forward_iterator
|
|
//
