class _Safe_sequence_base

__gnu_debug::_Safe_iterator_base::_Safe_iterator_base () [inline], [protected]¶

Initializes the iterator and makes it singular.

__gnu_debug::_Safe_iterator_base::_Safe_iterator_base (const _Safe_sequence_base * __seq, bool __constant) [inline], [protected]¶

Initialize the iterator to reference the sequence pointed to by __seq. __constant is true when we are initializing a constant iterator, and false if it is a mutable iterator. Note that __seq may be NULL, in which case the iterator will be singular. Otherwise, the iterator will reference __seq and be nonsingular.

References _M_attach().

__gnu_debug::_Safe_iterator_base::_Safe_iterator_base (const _Safe_iterator_base & __x, bool __constant) [inline], [protected]¶

Initializes the iterator to reference the same sequence that __x does. __constant is true if this is a constant iterator, and false if it is mutable.

References _M_attach(), and _M_sequence.

void __gnu_debug::_Safe_iterator_base::_M_attach (_Safe_sequence_base * __seq, bool __constant) [protected]¶

Attaches this iterator to the given sequence, detaching it from whatever sequence it was attached to originally. If the new sequence is the NULL pointer, the iterator is left unattached.

Referenced by _Safe_iterator_base(), _Safe_iterator_base(), and __gnu_debug::_Safe_iterator< _Iterator, _Sequence, _Category >::_M_attach().

void __gnu_debug::_Safe_iterator_base::_M_attach_single (_Safe_sequence_base * __seq, bool __constant) [protected]¶

Likewise, but not thread-safe.

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

bool __gnu_debug::_Safe_iterator_base::_M_attached_to (const _Safe_sequence_base * __seq) const [inline]¶

Determines if we are attached to the given sequence.

References _M_sequence.

bool __gnu_debug::_Safe_iterator_base::_M_can_compare (const _Safe_iterator_base & __x) const¶

Can we compare this iterator to the given iterator __x? Returns true if both iterators are nonsingular and reference the same sequence.

void __gnu_debug::_Safe_iterator_base::_M_detach () [protected]¶

Detach the iterator for whatever sequence it is attached to, if any.

void __gnu_debug::_Safe_iterator_base::_M_detach_single ()¶

Likewise, but not thread-safe.

__gnu_cxx::__mutex & __gnu_debug::_Safe_iterator_base::_M_get_mutex () [protected]¶

void __gnu_debug::_Safe_iterator_base::_M_invalidate () [inline]¶

Invalidate the iterator, making it singular.

void __gnu_debug::_Safe_iterator_base::_M_reset ()¶

Reset all member variables

bool __gnu_debug::_Safe_iterator_base::_M_singular () const¶

Is this iterator singular?

void __gnu_debug::_Safe_iterator_base::_M_unlink () [inline]¶

Unlink itself

_Safe_iterator_base* __gnu_debug::_Safe_iterator_base::_M_next¶

Pointer to the next iterator in the sequence's list of iterators. Only valid when _M_sequence != NULL.

Referenced by __gnu_debug::_Safe_sequence< _SafeSequence >::_M_invalidate_if(), __gnu_debug::_Safe_sequence< _Sequence >::_M_transfer_from_if(), and _M_unlink().

_Safe_iterator_base* __gnu_debug::_Safe_iterator_base::_M_prior¶

Pointer to the previous iterator in the sequence's list of iterators. Only valid when _M_sequence != NULL.

_Safe_sequence_base* __gnu_debug::_Safe_iterator_base::_M_sequence¶

The sequence this iterator references; may be NULL to indicate a singular iterator.

Referenced by _Safe_iterator_base(), __gnu_debug::_Safe_local_iterator_base::_Safe_local_iterator_base(), _M_attached_to(), __gnu_debug::_Safe_sequence< _Sequence >::_M_transfer_from_if(), __gnu_debug::_Safe_local_iterator< _Iterator, _Sequence >::operator++(), __gnu_debug::_Safe_iterator< _Iterator, _Sequence, _Category >::operator++(), __gnu_debug::_Safe_iterator< _Iterator, _Sequence, _Category >::operator=(), __gnu_debug::_Safe_local_iterator< _Iterator, _Sequence >::operator=(), __gnu_debug::_Safe_iterator< _Iterator, _Sequence, _Category >::operator=(), and __gnu_debug::_Safe_local_iterator< _Iterator, _Sequence >::operator=().

unsigned int __gnu_debug::_Safe_iterator_base::_M_version¶

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.
