Member Function Documentation
void __gnu_debug::_Safe_unordered_container_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], [protected],
[inherited]
Invalidates all iterators.

void __gnu_debug::_Safe_unordered_container< unordered_map< _Key, _Tp, _Hash, _Pred, _Alloc >
>::_M_invalidate_if (_Predicate __pred) [protected], [inherited]
Invalidates all iterators x that reference this container, are not singular, and for which
__pred(x) returns true. __pred will be invoked with the normal iterators nested in the
safe ones.
Definition at line 38 of file safe_unordered_container.tcc.
void __gnu_debug::_Safe_unordered_container< unordered_map< _Key, _Tp, _Hash, _Pred, _Alloc >
>::_M_invalidate_local_if (_Predicate __pred) [protected], [inherited]
Invalidates all local iterators x that reference this container, are not singular, and for
which __pred(x) returns true. __pred will be invoked with the normal ilocal iterators
nested in the safe ones.
Definition at line 70 of file safe_unordered_container.tcc.
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], [inherited]
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.
