The standard comparison function objects are partially specialized for std::experimental::propagate_const <T>

Let p.t_ denote the pointer-like object wrapped by a std::experimental::propagate_const <T> , then given objects p and q of type std::experimental::propagate_const <T>

• std::equal_to < std::experimental::propagate_const <T>> ( ) (p, q) == std::equal_to <T> ( ) (p.t_, q.t_ )
• std::not_equal_to < std::experimental::propagate_const <T>> ( ) (p, q) == std::not_equal_to <T> ( ) (p.t_, q.t_ )
• std::less < std::experimental::propagate_const <T>> ( ) (p, q) == std::less <T> ( ) (p.t_, q.t_ )
• std::greater < std::experimental::propagate_const <T>> ( ) (p, q) == std::greater <T> ( ) (p.t_, q.t_ )
• std::less_equal < std::experimental::propagate_const <T>> ( ) (p, q) == std::less_equal <T> ( ) (p.t_, q.t_ )
• std::greater_equal < std::experimental::propagate_const <T>> ( ) (p, q) == std::greater_equal <T> ( ) (p.t_, q.t_ )

Notes

These specializations ensure that when T is a pointer type, specializations of these class templates for std::experimental::propagate_const <T>
