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]
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
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.

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

References __gnu_debug::_Safe_sequence_base::_M_version.
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]
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], [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.
