std::experimental::basic_string_view Merged into ISO C++ The functionality described on this page was merged into the mainline ISO C++ standard as of 3/2016, see std::basic_string_view (since C++17) template<
class CharT,
class Traits = std::char_traits<CharT>
> class basic_string_view; (library fundamentals TS)
The class template basic_string_view describes an object that can refer to a constant contiguous sequence of char-like objects with the first element of the sequence at position zero.
A typical implementation holds only two members: a pointer to constant CharT and a size.
Several typedefs for common character types are provided:
Type Definition std::experimental::string_view std::experimental::basic_string_view<char> std::experimental::wstring_view std::experimental::basic_string_view<wchar_t> std::experimental::u16string_view std::experimental::basic_string_view<char16_t> std::experimental::u32string_view std::experimental::basic_string_view<char32_t> [edit] Template parameters CharT - character type Traits - traits class specifying the operations on the character type [edit] Member types Member type Definition traits_type Traits value_type CharT pointer CharT* const_pointer const CharT* reference CharT& const_reference const CharT& const_iterator implementation-defined LegacyRandomAccessIterator iterator const_iterator reverse_iterator const_reverse_iterator const_reverse_iterator std::reverse_iterator<const_iterator> size_type std::size_t difference_type std::ptrdiff_t
Note: iterator and const_iterator are the same type because string views are views into constant character sequences.
