* that tracks iterators that reference it.
|
|
*
|
|
* The class template %_Safe_unordered_container simplifies the
|
|
* construction of @a safe unordered containers that track the iterators
|
|
* that reference the container, so that the iterators are notified of
|
|
* changes in the container 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 @c const_iterator types that are instantiations of
|
|
* class template _Safe_iterator for this container and @c local_iterator
|
|
* and @c const_local_iterator types that are instantiations of class
|
|
* template _Safe_local_iterator for this container. Iterators will
|
|
* then be tracked automatically.
