Typedef Documentation

template<template< auto > typename F, typename L >

using SUNphi::FilterVariadicClassPos = typedef typename _FilterVariadicClass<F,L>::Pos

Get the position of elements of a vector, satisfying a condition

Gets a vector-like incapsulated list of variables, and returns a IntSeq containing the position of those that satisfy a certain condition.

Example:

 :

FilterVariadicClassPos<IsNotNull,IntSeq<0,1,0,10>>; // IntSeq<0,3>;

template<template< auto > typename F, auto... T>

using SUNphi::FilterVariadicList = typedef typename _FilterVariadicList<F, RangeSeq<0, 1, sizeof...(T)>, T...>::Res

Get the position of elements satisfying a rule.

Gets a set of variables as template parameter, and a condition F, returns the position of those which passes the filter F.
