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

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.

__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

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.

void __gnu_debug::_Safe_local_iterator_base::_M_attach_single ( _Safe_sequence_base __seq,

Likewise, but not thread-safe.

bool __gnu_debug::_Safe_iterator_base::_M_attached_to ( const _Safe_sequence_base __seq) const [inline, inherited]

Determines if we are attached to the given sequence.

bool __gnu_debug::_Safe_iterator_base::_M_can_compare ( const _Safe_iterator_base __x) const throw () [inherited]

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

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

Reimplemented from __gnu_debug::_Safe_iterator_base.

For use in _Safe_iterator.

Invalidate the iterator, making it singular.

Member Data Documentation

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

Definition at line 73 of file safe_base.h.

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

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

Definition at line 69 of file safe_base.h.

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

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.
