Detailed Description
Basic functionality for a safe iterator.
The _Safe_local_iterator_base base class implements the functionality of a safe local iterator that is
not specific to a particular iterator type. It contains a pointer back to the container it references
along with iterator version information and pointers to form a doubly-linked list of local iterators
referenced by the container.
This class must not perform any operations that can throw an exception, or the exception guarantees of
derived iterators will be broken.
Constructor & Destructor Documentation
__gnu_debug::_Safe_local_iterator_base::_Safe_local_iterator_base () [inline], [protected]
Initializes the iterator and makes it singular.
Referenced by _Safe_local_iterator_base().
__gnu_debug::_Safe_local_iterator_base::_Safe_local_iterator_base (const _Safe_sequence_base * __seq, bool
__constant) [inline], [protected]
Initialize the iterator to reference the container pointed to by __seq. __constant is true when we are
initializing a constant local iterator, and false if it is a mutable local 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_local_iterator_base::_Safe_local_iterator_base (const _Safe_local_iterator_base & __x,
bool __constant) [inline], [protected]
Initializes the iterator to reference the same container that __x does. __constant is true if this is a
constant iterator, and false if it is mutable.

Member Function Documentation
void __gnu_debug::_Safe_local_iterator_base::_M_attach (_Safe_sequence_base * __seq, bool __constant)

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

bool __gnu_debug::_Safe_iterator_base::_M_can_compare (const _Safe_iterator_base & __x) const [inherited]
Can we compare this iterator to the given iterator __x? Returns true if both iterators are nonsingular
and reference the same sequence.

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.
