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.
Definition at line 54 of file safe_unordered_base.h.
__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.
Definition at line 64 of file safe_unordered_base.h.
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.

Determines if we are attached to the given 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.

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.
