std::experi...eater_equal(3)  C++ Standard Libary std::experi...eater_equal(3)

NAME
       std::experimental::ranges::greater_equal	       -       std::experimen-
       tal::ranges::greater_equal

Synopsis
	  Defined in header <experimental/ranges/functional>
	  template< class T = void >

	  requires StrictTotallyOrdered<T> ||
	  Same<T,			    void>			    ||
       (ranges TS)
	  /* < on two const T lvalues invokes a	built-in operator comparing
	  pointers */

	  struct greater_equal;
	  template							    <>
       (ranges TS)
	  struct greater_equal<void>;

	  Function object for performing comparisons. The primary template in-
       vokes operator<
	  on const lvalues of type T and negates the result.  The  specializa-
       tion
	  greater_equal<void> deduces the parameter types of the function call
       operator	from
	  the arguments	(but not the return type).

	  All specializations of greater_equal are Semiregular.

Member types
	  Member							  type
       Definition
	  is_transparent (member only of  greater_equal<void>  specialization)
       /* unspecified */

Member functions
	  operator()  checks if	the first argument is greater than or equal to
       the second
		     (public member function)

       std::experimental::ranges::greater_equal::operator()

	  constexpr bool operator()(const T& x,	const  T&  y)	  (1)  (member
       only of primary
	  const;
       greater_equal<T>	template)
	  template< class T, class U >

	  requires  StrictTotallyOrderedWith<T,	 U>  ||		       (member
       only of
	  /*   std::declval<T>()   <   std::declval<U>()   resolves   to   (2)
       greater_equal<void>
	  a built-in operator comparing	pointers */		   specializa-
       tion)

	  constexpr bool operator()(T&&	t, U&& u) const;

	  1) Compares x	and y. Equivalent to return !ranges::less<>{}(x, y);
	  2)	 Compares     t	    and	    u.	   Equivalent	  to	return
       !ranges::less<>{}(std::forward<T>(t),
	  std::forward<U>(u));.

Notes
	  Unlike std::greater_equal, ranges::greater_equal  requires  all  six
       comparison
	  operators  <,	<=, >, >=, == and != to	be valid (via the StrictTotal-
       lyOrdered and
	  StrictTotallyOrderedWith constraints)	and  is	 entirely  defined  in
       terms of
	  ranges::less.	 However, the implementation is	free to	use operator>=
       directly,
	  because those	concepts require the results of	the comparison	opera-
       tors to be
	  consistent.

Example
	   This	section	is incomplete
	   Reason: no example
