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.

Referenced by __gnu_debug::_Safe_sequence< _Sequence >::_M_transfer_from_if().

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

References __gnu_debug::_Safe_sequence_base::_M_version.

  template<typename _Container > template<typename _Predicate > void __gnu_debug::_Safe_unordered_container< _Container >::_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.

  template<typename _Container > template<typename _Predicate > void __gnu_debug::_Safe_unordered_container< _Container >::_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 local iterators nested in the safe ones.

  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], [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.
