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.

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

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.

template<typename _Sequence > template<typename _Predicate > void
__gnu_debug::_Safe_sequence< _Sequence >::_M_invalidate_if (_Predicate
__pred) [inline] 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.

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) [inline] Transfers all
iterators that reference this memory location to this sequence from
whatever sequence they are attached to.
