WithIdxSeq< N > Class Template Reference

#include "lib/meta/variadic-helper.hpp"

Description

template<size_t N>
class lib::meta::WithIdxSeq< N >

helper to invoke a functor, passing instances of std::integral_constant

Template Parameters

N	size of the index-sequence to use for instantiation

Remarks

the functor is given for...

• to be invoked either (as void) for each index
• or as a predicate, combining the results with AND / OR
