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. Definition at line 50 of file safe_unordered_base.h. 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.

The sentinel value 0 is used to indicate an invalidated iterator (i.e., one that is singular because of an operation on the container).
