Base class that supports tracking of iterators that reference a sequence.

The _Safe_sequence_base class provides basic support for tracking iterators into a sequence. Sequences that track iterators must derived from _Safe_sequence_base publicly, so that safe iterators (which inherit _Safe_iterator_base) can attach to them. This class contains two linked lists of iterators, one for constant iterators and one for mutable 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 sequences may fail to provide the exception-safety guarantees required by the C++ standard.

_M_detach_all()

void __gnu_debug::_Safe_sequence_base::_M_detach_all ( ) protected

_M_detach_singular()

void __gnu_debug::_Safe_sequence_base::_M_detach_singular ( ) protected

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

_M_invalidate_all()

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

_M_revalidate_singular()

void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular ( ) protected

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()

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_const_iterators

_M_iterators

_M_version

unsigned int __gnu_debug::_Safe_sequence_base::_M_version mutable

The container version number. This number may never be 0.
