The class template _Safe_sequence simplifies the construction of \fIsafe\fP sequences that track the iterators that reference the sequence, so that the iterators are notified of changes in the sequence 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 \fRiterator\fP and \fRconst_iterator\fP types that are instantiations of class template _Safe_iterator for this sequence\&. Iterators will then be tracked automatically\&. .SH "Member Function Documentation" .PP .SS "void __gnu_debug::_Safe_sequence_base::_M_detach_all ()\fR [protected]\fP, \fR [inherited]\fP" Detach all iterators, leaving them singular\&. .PP Referenced by \fB__gnu_debug::_Safe_sequence_base::~_Safe_sequence_base()\fP\&. .SS "void __gnu_debug::_Safe_sequence_base::_M_detach_singular ()\fR [protected]\fP, \fR [inherited]\fP" Detach all singular iterators\&. .PP \fBPostcondition\fP .RS 4 for all iterators i attached to this sequence, i->_M_version == _M_version\&. .RE .PP .SS "__gnu_cxx::__mutex & __gnu_debug::_Safe_sequence_base::_M_get_mutex ()\fR [protected]\fP, \fR [inherited]\fP" For use in _Safe_sequence\&. .PP Referenced by \fB__gnu_debug::_Safe_sequence< _Sequence >::_M_transfer_from_if()\fP\&. .SS "void __gnu_debug::_Safe_sequence_base::_M_invalidate_all () const\fR [inline]\fP, \fR [protected]\fP, \fR [inherited]\fP" Invalidates all iterators\&. .PP References \fB__gnu_debug::_Safe_sequence_base::_M_version\fP\&. .SS "template template void \fB__gnu_debug::_Safe_sequence\fP< _Sequence >::_M_invalidate_if (_Predicate __pred)" Invalidates all iterators \fRx\fP that reference this sequence, are not singular, and for which \fR__pred(x)\fP returns \fRtrue\fP\&. \fR__pred\fP will be invoked with the normal iterators nested in the safe ones\&. .SS "void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular ()\fR [protected]\fP, \fR [inherited]\fP" Revalidates all attached singular iterators\&.
