Detailed Description

GNU debug classes for public use.

Typedef Documentation

  typedef basic_string<char16_t> __gnu_debug::u16string

A string of char16_t.

  typedef basic_string<char32_t> __gnu_debug::u32string

A string of char32_t.

Enumeration Type Documentation

  enum __gnu_debug::_Distance_precision
The precision to which we can calculate the distance between two iterators.

Function Documentation

  template<typename _Iterator> _Iterator __gnu_debug::__base (_Iterator __it) [inline], [constexpr]
Helper function to extract base iterator of random access safe iterator in order to reduce performance impact of debug mode. Limited to random access iterator because it is the only category for which it is possible to check for correct iterators order in the __valid_range function thanks to the < operator.

Referenced by __gnu_debug::_Safe_iterator< _Base_iterator, map >::_M_before_dereferenceable().

  template<typename _Tp> bool __gnu_debug::__check_singular (_Tp *const & __ptr) [inline], [constexpr]
Non-NULL pointers are nonsingular.

  bool __gnu_debug::__check_singular_aux (const _Safe_iterator_base * __x) [inline]
Iterators that derive from _Safe_iterator_base can be determined singular or non-singular.

References __gnu_debug::_Safe_iterator_base::_M_singular().

  template<typename _CharT, typename _Integer> const _CharT * __gnu_debug::__check_string (const _CharT * __s, _Integer __n, const char * __file, unsigned int __line, const char * __function) [inline]
Checks that __s is non-NULL or __n == 0, and then returns __s.

  template<typename _CharT> const _CharT * __gnu_debug::__check_string (const _CharT * __s, const char * __file, unsigned int __line, const char * __function) [inline]
Checks that __s is non-NULL and then returns __s.

  template<typename _Iterator, typename _Sequence, typename _Category, typename _OtherIterator, typename _OtherSequence, typename _OtherCategory> bool __gnu_debug::__foreign_iterator_aux2 (const _Safe_iterator< _Iterator, _Sequence, _Category > & , const _Safe_iterator< _OtherIterator, _OtherSequence, _OtherCategory > & , const _Safe_iterator< _OtherIterator, _OtherSequence, _OtherCategory > & ) [inline]
Handle debug iterators from different types of container.

  template<typename _Iterator, typename _Sequence, typename _Category, typename _OtherIterator> bool __gnu_debug::__foreign_iterator_aux2 (const _Safe_iterator< _Iterator, _Sequence, _Category > & __it, const _Safe_iterator< _OtherIterator, _Sequence, _Category > & __other, const _Safe_iterator< _OtherIterator, _Sequence, _Category > & ) [inline]
Handle debug iterators from the same type of container.

  template<typename _Iterator> _Distance_traits< _Iterator >::__type __gnu_debug::__get_distance (_Iterator __lhs, _Iterator __rhs, std::random_access_iterator_tag ) [inline], [constexpr]
Determine the distance between two iterators with some known precision.

References std::make_pair().

  template<typename _InputIterator> bool __gnu_debug::__valid_range (_InputIterator __first, _InputIterator __last, typename _Distance_traits< _InputIterator >::__type & __dist) [inline], [constexpr]
Don't know what these iterators are, or if they are even iterators (we may get an integral type for InputIterator), so see if they are integral and pass them on to the next phase otherwise.

References __valid_range_aux().

  template<typename _Iterator, typename _Sequence, typename _Category> bool __gnu_debug::__valid_range (const _Safe_iterator< _Iterator, _Sequence, _Category > & __first, const _Safe_iterator< _Iterator, _Sequence, _Category > & __last, typename _Distance_traits< _Iterator >::__type & __dist) [inline]
Safe iterators know how to check if they form a valid range.

  template<typename _Iterator, typename _Sequence> bool __gnu_debug::__valid_range (const _Safe_local_iterator< _Iterator, _Sequence > & __first, const _Safe_local_iterator< _Iterator, _Sequence > & __last, typename _Distance_traits< _Iterator >::__type & __dist_info) [inline]
Safe local iterators know how to check if they form a valid range.

  template<typename _InputIterator> bool __gnu_debug::__valid_range_aux (_InputIterator __first, _InputIterator __last, std::__false_type ) [inline], [constexpr]
We have iterators, so figure out what kind of iterators they are to see if we can check the range ahead of time.

References std::__iterator_category(), and __valid_range_aux().

  template<typename _Integral> bool __gnu_debug::__valid_range_aux (_Integral , _Integral , std::__true_type ) [inline], [constexpr]
We say that integral types for a valid range, and defer to other routines to realize what to do with integral types instead of iterators.
