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.

constexpr __gnu_debug::_Safe_iterator_base::_Safe_iterator_base ( )	inlineconstexprprotected

Initializes the iterator and makes it singular.

Definition at line 79 of file safe_base.h.

◆ _Safe_iterator_base() [2/3]

constexpr __gnu_debug::_Safe_iterator_base::_Safe_iterator_base ( const _Safe_sequence_base * __seq, bool __constant )	inlineconstexprprotected

Initialize the iterator to reference the sequence pointed to by __seq. __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.

◆ _Safe_iterator_base() [3/3]

constexpr __gnu_debug::_Safe_iterator_base::_Safe_iterator_base ( const _Safe_iterator_base & __x, bool __constant )	inlineconstexprprotected

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.

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

◆ _Safe_sequence_base

◆ _M_next

◆ _M_prior

◆ _M_sequence

The sequence this iterator references; may be NULL to indicate a singular iterator.

Definition at line 57 of file safe_base.h.

◆ _M_version

unsigned int __gnu_debug::_Safe_iterator_base::_M_version

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.
