Detailed Description

       Base class that supports tracking of local iterators that reference an unordered
       container.

       The _Safe_unordered_container_base class provides basic support for tracking iterators
       into an unordered container. Containers that track iterators must derived from
       _Safe_unordered_container_base publicly, so that safe iterators (which inherit
       _Safe_iterator_base) can attach to them. This class contains four linked lists of
       iterators, one for constant iterators, one for mutable iterators, one for constant local
       iterators, one for mutable local 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
       containers may fail to provide the exception-safety guarantees required by the C++
       standard.

Constructor & Destructor Documentation

   __gnu_debug::_Safe_unordered_container_base::~_Safe_unordered_container_base () [inline],
       [protected],  [noexcept]
       Notify all iterators that reference this container that the container is being destroyed.

   void __gnu_debug::_Safe_sequence_base::_M_attach (_Safe_iterator_base * __it, bool __constant)
       [inherited]
       Attach an iterator to this sequence.

   void __gnu_debug::_Safe_unordered_container_base::_M_attach_local (_Safe_iterator_base * __it,
       bool __constant)
       Attach an iterator to this container.

   void __gnu_debug::_Safe_unordered_container_base::_M_attach_local_single (_Safe_iterator_base
       * __it, bool __constant)
       Likewise but not thread safe.

   void __gnu_debug::_Safe_sequence_base::_M_attach_single (_Safe_iterator_base * __it, bool
       __constant) [inherited]
       Likewise but not thread safe.

   void __gnu_debug::_Safe_sequence_base::_M_detach (_Safe_iterator_base * __it) [inherited]
       Detach an iterator from this sequence

       Referenced by __gnu_debug::_Safe_iterator< _Iterator, _Sequence >::_Safe_iterator().

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

   void __gnu_debug::_Safe_unordered_container_base::_M_detach_local (_Safe_iterator_base * __it)
       Detach an iterator from this container

   void __gnu_debug::_Safe_unordered_container_base::_M_detach_local_single (_Safe_iterator_base
       * __it)
       Likewise but not thread safe.

   void __gnu_debug::_Safe_sequence_base::_M_detach_single (_Safe_iterator_base * __it)
       [inherited]
       Likewise but not thread safe.

   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.

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

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

       __gnu_debug::_Safe_iterator_base::_M_detach_single().

   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_unordered_container_base::_M_swap (_Safe_unordered_container_base &
       __x) [protected],  [noexcept]
       Swap this container with the given container. 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.

   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.
