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 ( ) const
protectedinherited

Detach all iterators, leaving them singular.

◆ _M_detach_singular()

void __gnu_debug::_Safe_sequence_base::_M_detach_singular ( ) const
protectedinherited

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 ( ) const
protectednoexceptinherited

For use in _Safe_sequence.

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

◆ _M_invalidate_all()

constexpr void __gnu_debug::_Safe_sequence_base::_M_invalidate_all ( ) const
inlineconstexprprotectedinherited

Invalidates all iterators.

Definition at line 314 of file safe_base.h.

References __gnu_debug::_Safe_sequence_base::_M_version.

◆ _M_revalidate_singular()

void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular ( ) const
protectedinherited

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_sequence_base::_M_swap ( const _Safe_sequence_base &  __x) const
protectednoexceptinherited

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.

◆ _M_swap() [2/2]

void __gnu_debug::_Safe_unordered_container_base::_M_swap ( const _Safe_unordered_container_base &  __x) const
protectednoexceptinherited

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.
