Detailed Description
       Base class that supports tracking of iterators that reference a
       sequence.

       The _Safe_sequence_base class provides basic support for tracking
       iterators into a sequence. Sequences that track iterators must derived
       from _Safe_sequence_base publicly, so that safe iterators (which
       inherit _Safe_iterator_base) can attach to them. This class contains
       two linked lists of iterators, one for constant iterators and one for
       mutable iterators, and a version number that allows very fast
       invalidation of all iterators that reference the container.

       This class must ensure that no operation on it may throw an exception,
       otherwise safe sequences may fail to provide the exception-safety
       guarantees required by the C++ standard.

Constructor & Destructor Documentation
   __gnu_debug::_Safe_sequence_base::~_Safe_sequence_base () [inline],
       [protected]
       Notify all iterators that reference this sequence that the sequence is
       being destroyed.

       References _M_detach_all().

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

       Referenced by ~_Safe_sequence_base().

   void __gnu_debug::_Safe_sequence_base::_M_detach_singular () [protected]
       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]
       For use in _Safe_sequence.

       Referenced by __gnu_debug::_Safe_sequence< _Sequence
       >::_M_transfer_from_if().

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

       References _M_version.

   void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular ()
       [protected]
       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],  [noexcept]
       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.
