Detailed Description

template<typename T>
struct has_grid_type< T, typename Void< decltype(T::grid_type)>::type >

has_grid_type check if T has defined the member grid_type

Define structures with information inside

 
struct test_grid_type_staggered
{
    static const int grid_type = STAGGERED_GRID;
};
 
struct test_grid_type_normal
{
    static const int grid_type = NORMAL_GRID;
};
 
struct test_grid_type_no_def
{
};
 

Usage on the defined structures

 
    BOOST_REQUIRE_EQUAL(has_grid_type<test_grid_type_staggered>::type::value,true);
    BOOST_REQUIRE_EQUAL(has_grid_type<test_grid_type_normal>::type::value,true);
    BOOST_REQUIRE_EQUAL(has_grid_type<test_grid_type_no_def>::type::value,false);
