Detailed Description

template<template< class, class > class F, class Tuple, class Seed = tuple<>, int N = tuple_size<Tuple>::value>
struct Dune::ReduceTuple< F, Tuple, Seed, N >

Apply reduce with meta binary function to template.

For a tuple<T0,T1,...,TN-1,TN,...> the exported result is

F< ... F< F< F<Seed,T0>::type, T1>::type, T2>::type, ... TN-1>::type

Template Parameters

F	Binary meta function
Tuple	Apply reduce operation to this tuple
Seed	Initial value for reduce operation
N	Reduce the first N tuple elements
