Member Data Documentation¶
_Safe_iterator_base* __gnu_debug::_Safe_iterator_base::_M_next [inherited]¶
Pointer to the next iterator in the sequence's list of
iterators. Only valid when _M_sequence != NULL. Definition at line 73 of file safe_base.h. Referenced by __gnu_debug::_Safe_sequence< _Sequence >::_M_transfer_from_if(), and __gnu_debug::_Safe_iterator_base::_M_unlink().
_Safe_iterator_base* __gnu_debug::_Safe_iterator_base::_M_prior [inherited]¶
Pointer to the previous iterator in the sequence's list of
iterators. Only valid when _M_sequence != NULL. Definition at line 69 of file safe_base.h. Referenced by __gnu_debug::_Safe_sequence< _Sequence >::_M_transfer_from_if(), and __gnu_debug::_Safe_iterator_base::_M_unlink().
_Safe_sequence_base* __gnu_debug::_Safe_iterator_base::_M_sequence [inherited]¶
The sequence this iterator references; may be NULL to indicate
a singular iterator. Definition at line 56 of file safe_base.h. Referenced by __gnu_debug::_Safe_iterator_base::_M_attached_to(), __gnu_debug::_Safe_sequence< _Sequence >::_M_transfer_from_if(), __gnu_debug::_Safe_iterator_base::_Safe_iterator_base(), and __gnu_debug::_Safe_iterator< _Iterator, _Sequence >::operator=().
unsigned int __gnu_debug::_Safe_iterator_base::_M_version [inherited]¶
The version number of this iterator. The sentinel value 0 is used to indicate an invalidated iterator (i.e., one that is singular because of an operation on the container). This version number must equal the version number in the sequence referenced by _M_sequence for the iterator to be non-singular. Definition at line 65 of file safe_base.h.
