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 const_iterator 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],  [protected],
       [inherited]
       Invalidates all iterators.

   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. __pred will be invoked with the normal iterators nested in the
       safe ones.

       Definition at line 37 of file safe_sequence.tcc.

   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],
       [noexcept],  [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 _Predicate > void __gnu_debug::_Safe_sequence<
       _Sequence >::_M_transfer_from_if (_Safe_sequence< _Sequence > & __from, _Predicate __pred)
       Transfers all iterators x that reference from sequence, are not singular, and for which
       __pred(x) returns true. __pred will be invoked with the normal iterators nested in the
       safe ones.
