## Detailed Description

### template<typename _Container>
class __gnu_debug::_Safe_unordered_container< _Container >

Base class for constructing a safe unordered container type that tracks iterators that reference it.

The class template _Safe_unordered_container simplifies the construction of safe unordered containers that track the iterators that reference the container, so that the iterators are notified of changes in the container that may affect their operation, e.g., if the container invalidates its iterators or is destructed. This class template may only be used by deriving from it and passing the name of the derived class as its template parameter via the curiously recurring template pattern. The derived class must have `iterator` and `const_iterator` types that are instantiations of class template _Safe_iterator for this container and `local_iterator` and `const_local_iterator` types that are instantiations of class template _Safe_local_iterator for this container. Iterators will then be tracked automatically.

## Member Function Documentation

## _M_detach_all()

void __gnu_debug::_Safe_unordered_container_base::_M_detach_all | ( |  | ) |

protected inherited

Detach all iterators, leaving them singular.

## _M_detach_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.

## _M_get_mutex()

__gnu_cxx::__mutex& __gnu_debug::_Safe_sequence_base::_M_get_mutex | ( |  | ) |
throw | ( |
| ) |  |

protected inherited

For use in _Safe_sequence.

Referenced by __gnu_debug::_Safe_sequence< map< _Key, _Tp, _Compare, _Allocator > >::_M_transfer_from_if().

## _M_invalidate_all()

void __gnu_debug::_Safe_sequence_base::_M_invalidate_all | ( |  | ) | const

inline protected inherited

Invalidates all iterators.

## _M_invalidate_if()

template<typename _Container >
template<typename _Predicate >

void __gnu_debug::_Safe_unordered_container< _Container >::_M_invalidate_if | ( | _Predicate | __pred | ) |

protected

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.

## _M_invalidate_local_if()

template<typename _Container >
template<typename _Predicate >

void __gnu_debug::_Safe_unordered_container< _Container >::_M_invalidate_local_if | ( | _Predicate | __pred | ) |

protected

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.

Referenced by __gnu_debug::_Safe_unordered_container< unordered_set< _Value, _Hash, _Pred, _Alloc > >::_M_invalidate_if().

## _M_revalidate_singular()

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).

## _M_swap() [1/2]

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.

## _M_swap() [2/2]

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.
