Detailed Description

   template<typename _Sequence>class __gnu_debug::_Safe_sequence< _Sequence >
       Base class for constructing a 'safe' sequence type that tracks iterators that reference it.

       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 iterator and  types
       that are instantiations of class template _Safe_iterator for this sequence. Iterators will then be
       tracked automatically.

   void __gnu_debug::_Safe_sequence_base::_M_detach_all () [protected],  [inherited]
       Detach all iterators, leaving them singular.

       Referenced by __gnu_debug::_Safe_sequence_base::~_Safe_sequence_base().

   void __gnu_debug::_Safe_sequence_base::_M_detach_singular () [protected],  [inherited]
       Detach all singular iterators.

       Postcondition:
           for all iterators i attached to this sequence, i->_M_version == _M_version.

   __gnu_cxx::__mutex& __gnu_debug::_Safe_sequence_base::_M_get_mutex () [protected],  [inherited]
       For use in _Safe_sequence.

   void __gnu_debug::_Safe_sequence_base::_M_invalidate_all () const [inline],  [inherited]
       Invalidates all iterators.

       Definition at line 215 of file safe_base.h.

   template<typename _Sequence > template<typename _Predicate > void __gnu_debug::_Safe_sequence< _Sequence
       >::_M_invalidate_if (_Predicate__pred)
       Invalidates all iterators x that reference this sequence, are not singular, and for which pred(x) returns
       true. The user of this routine should be careful not to make copies of the iterators passed to pred, as
       the copies may interfere with the invalidation.

       Definition at line 121 of file safe_sequence.h.

   void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular () [protected],  [inherited]
       Revalidates all attached singular iterators. This method may be used to validate iterators that were
       invalidated before (but for some reason, such as an exception, need to become valid again).

   void __gnu_debug::_Safe_sequence_base::_M_swap (_Safe_sequence_base &__x) [protected],  [inherited]
       Swap this sequence with the given sequence. This operation also swaps ownership of the iterators, so that
       when the operation is complete all iterators that originally referenced one container now reference the
       other container.

   template<typename _Sequence> template<typename _Iterator > void __gnu_debug::_Safe_sequence< _Sequence
       >::_M_transfer_iter (const _Safe_iterator< _Iterator, _Sequence > &__x)
       Transfers all iterators that reference this memory location to this sequence from whatever sequence they
       are attached to.
