__gnu_debug::_safe_iterator_base(3)
NAME
__gnu_debug::_Safe_iterator_base
SYNOPSIS
Inherited by __gnu_debug::_Safe_iterator< _Iterator, _Sequence >, and std::__debug::bitset< _Nb >::reference.
Detailed Description
Basic functionality for a 'safe' iterator.
The _Safe_iterator_base base class implements the functionality of a
safe iterator that is not specific to a particular iterator type. It
contains a pointer back to the sequence it references along with
iterator version information and pointers to form a doubly-linked list
of 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_iterator_base::_Safe_iterator_base () [inline,
- protected]
Initializes the iterator and makes it singular. - Definition at line 82 of file safe_base.h.
- __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 .
__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. - Definition at line 93 of file safe_base.h.
- 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. - Definition at line 100 of file safe_base.h.

Member Function Documentation
- void __gnu_debug::_Safe_iterator_base::_M_attach (_Safe_sequence_base *
- __seq, bool __constant)
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 __gnu_debug::_Safe_iterator< _Iterator, _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 ()
- Detach the iterator for whatever sequence it is attached to, if any.

- 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 70 of file safe_base.h.
