- * The class template %_Safe_sequence simplifies the construction of |
- * "safe" sequences that track the iterators that reference the |
- * sequence, so that the iterators are notified of changes in the |
- * sequence that may affect their operation, e.g., if the container |
- * invalidates its iterators or is destructed. This class template |
- * may only be used by deriving from it and passing the name of the |
- * derived class as its template parameter via the curiously |
- * recurring template pattern. The derived class must have @c |
- * iterator and @const_iterator types that are instantiations of |
- * class template _Safe_iterator for this sequence. Iterators will |
- * then be tracked automatically. |
