max_flat

max_flat_t kumi::max_flat {}

inlineconstexprnodiscardnoexcept

Callable object computing the maximum value of applications of f to all elements of kumi::flatten_all(t).

Header file

#include <kumi/algorithm/minmax.hpp>

Call Signature

template<product_type T, typename Function>
constexpr auto max_flat(T && t, Function f) noexcept;

Parameters

• t: Product Type to inspect
• f: Unary callable object to be invoked

Return value

• The minimum value of f over all elements of a flattened version of t

Helper type

    //
    template<typename T, typename F> using max_flat_t = decltype(kumi::max_flat(std::declval<T>(), std::declval<F>()));
 
    template<typename T, typename F> struct max_flat
    {
      using type = kumi::result::max_flat_t<T, F>;
    };
 

Computes the return type of a call to kumi::max_flat

Examples

• Tuple

  
  #include <kumi/kumi.hpp>
  #include <iostream>
   
  int main()
  {
    auto f0 = kumi::tuple {2., kumi::tuple {1., 'u', 3. }, 3.f };
   
    std::cout << kumi::max_flat (f0 , [](auto m) { return sizeof(m); }) << "\n";
  }

• Record

  
  #include <kumi/kumi.hpp>
  #include <iostream>
   
  int main()
  {
    using namespace kumi::literals;
    auto f0 = kumi::record {"a"_id = 2., "b"_id = 
      kumi::record {"c"_id = 1., "d"_id = 'u', "e"_id = 3. }, "f"_id = 3.f };
   
    std::cout << kumi::max_flat (f0 , [](auto m) { return sizeof(m); }) << "\n";
  }
