Detailed Description

template<typename _Iterator, typename _Sequence>
class __gnu_debug::_Safe_iterator< _Iterator, _Sequence >

Safe iterator wrapper.

The class template _Safe_iterator is a wrapper around an iterator that tracks the iterator's movement among sequences and checks that operations performed on the "safe" iterator are legal. In additional to the basic iterator operations (which are validated, and then passed to the underlying iterator), _Safe_iterator has member functions for iterator invalidation, attaching/detaching the iterator from sequences, and querying the iterator's state.

Note that _Iterator must be the first base class so that it gets initialized before the iterator is being attached to the container's list of iterators and it is being detached before _Iterator get destroyed. Otherwise it would result in a data race.

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.

Referenced by __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.

Referenced by __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.

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.

Referenced by __gnu_debug::_Safe_local_iterator< _Iterator, _Sequence >::operator=(), and __gnu_debug::_Safe_iterator< _Iterator, _Sequence >::operator=().
