Detailed Description

template<template< typename > class H, typename L>
struct v_transform< H, L >

It transform a boost::fusion::vector to another boost::fusion::vector applying a meta-function H on each element

Parameters

H	metafunction (is a structure with typedef type)
L	boost::fusion::vector

Meta-function definition

template <typename T>
struct F
{
    typedef aggregate<T> type;
};

Usage

 
    typedef boost::mpl::vector<float,float,float[3]> bfv;
 
    // tbvf is boost::fusion::vector<scalar<float>,scalar<float>,scalar<float[3]>>
    typedef v_transform<F,bfv>::type tbfv;
 
    bool val = std::is_same<boost::mpl::at<tbfv,boost::mpl::int_<0>>::type,aggregate<float>>::value;
    BOOST_REQUIRE_EQUAL(val,true);
 
    val = std::is_same<boost::mpl::at<tbfv,boost::mpl::int_<1>>::type,aggregate<float>>::value;
    BOOST_REQUIRE_EQUAL(val,true);
 
    val = std::is_same<boost::mpl::at<tbfv,boost::mpl::int_<2>>::type,aggregate<float[3]>>::value;
    BOOST_REQUIRE_EQUAL(val,true);
