__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.
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.

Member Function Documentation
void__gnu_debug::_Safe_unordered_container_base::_M_detach_all()[protected]
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],[protected],[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_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.
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.
