std::char_traits<CharT>::eq,std::char_traits<CharT>::lt: std::char_traits<CharT>::eq,std::char_traits<CharT>::lt

NAME

std::char_traits<CharT>::eq,std::char_traits<CharT>::lt - std::char_traits<CharT>::eq,std::char_traits<CharT>::lt

Synopsis

static bool eq( char_type a, char_type b ); (until C++11)
static constexpr bool eq( char_type a, char_type b ) noexcept; (1) (since C++11)
static bool lt( char_type a, char_type b ); (2) (until C++11)
static constexpr bool lt( char_type a, char_type b ) noexcept; (since C++11)

Compares two characters.
1) Compares a and b for equality.
2) Compares a and b in such a way that they are totally ordered.

For the char specialization, eq and lt are defined identically to the built-in operators == and < for type unsigned char (not char). (since C++11)

Parameters

a, b - character values to compare

Return value

1) true if a and b are equal, false otherwise.
2) true if a is less than b, false otherwise.

Complexity

Constant.
