Detailed Description
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.

Constructor & Destructor Documentation
- __gnu_debug::_Safe_sequence_base::~_Safe_sequence_base () [inline,
- protected]
Notify all iterators that reference this sequence that the sequence is being destroyed. - Definition at line 184 of file safe_base.h.
- References _M_detach_all().
Member Function Documentation
- void __gnu_debug::_Safe_sequence_base::_M_detach_all () [protected]
- Detach all iterators, leaving them singular.
- Referenced by ~_Safe_sequence_base().
- 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. - __gnu_cxx::__mutex& __gnu_debug::_Safe_sequence_base::_M_get_mutex ()
- [protected]
For use in _Safe_sequence. - Referenced by __gnu_debug::_Safe_sequence< _Sequence
>::_M_invalidate_if(), and __gnu_debug::_Safe_sequence< _Sequence
>::_M_transfer_iter(). - void __gnu_debug::_Safe_sequence_base::_M_invalidate_all () const [inline]
- Invalidates all iterators.
- Definition at line 220 of file safe_base.h.
- References _M_version.
- 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). - void __gnu_debug::_Safe_sequence_base::_M_swap (_Safe_sequence_base & __x)
- [protected]
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.
