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.

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] |
