Detailed Description

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.

Constructor & Destructor Documentation

__gnu_debug::_Safe_unordered_container_base::~_Safe_unordered_container_base ( )

inlineprotectednoexcept

Notify all iterators that reference this container that the container is being destroyed.

void __gnu_debug::_Safe_sequence_base::_M_attach	(	_Safe_iterator_base *	__it,
		bool	__constant
	)

inherited

Attach an iterator to this sequence.

void __gnu_debug::_Safe_unordered_container_base::_M_attach_local	(	_Safe_iterator_base *	__it,
		bool	__constant
	)

Attach an iterator to this container.

void __gnu_debug::_Safe_unordered_container_base::_M_attach_local_single	(	_Safe_iterator_base *	__it,
		bool	__constant
	)
throw	(
	)

Likewise but not thread safe.

void __gnu_debug::_Safe_sequence_base::_M_attach_single	(	_Safe_iterator_base *	__it,
		bool	__constant
	)
throw	(
	)

inherited

Likewise but not thread safe.

void __gnu_debug::_Safe_sequence_base::_M_detach ( _Safe_iterator_base * __it )

inherited

Detach an iterator from this sequence

Referenced by __gnu_debug::_Safe_iterator< _Iterator, _Sequence >::_Safe_iterator().

void __gnu_debug::_Safe_unordered_container_base::_M_detach_all ( )

protected

Detach all iterators, leaving them singular.

void __gnu_debug::_Safe_unordered_container_base::_M_detach_local ( _Safe_iterator_base * __it )

Detach an iterator from this container

void __gnu_debug::_Safe_unordered_container_base::_M_detach_local_single	(	_Safe_iterator_base *	__it	)
throw	(
	)

Likewise but not thread safe.

void __gnu_debug::_Safe_sequence_base::_M_detach_single	(	_Safe_iterator_base *	__it	)
throw	(
	)

inherited

Likewise but not thread safe.

void __gnu_debug::_Safe_sequence_base::_M_detach_singular ( )

protectedinherited

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	(	)
throw	(
	)

protectedinherited

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

inlineinherited

Invalidates all iterators.

void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular ( )

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).

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

protectednoexcept

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 )

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.
