Detailed Description

template<typename T>
struct has_typedef_type< T, typename Void< typename T::type >::type >

has_typedef_type check if a typedef ... type inside the structure is defined

Example

 
        struct test_has_typedef
        {
            typedef float type;
        };
 
        struct test_no_has_data
        {
        };
 
        int val = has_typedef_type<test_has_typedef>::value;
        BOOST_REQUIRE_EQUAL(val, true);
        val = has_typedef_type<test_no_has_data>::value;
        BOOST_REQUIRE_EQUAL(val, false);
 

return true if T::type is a valid type
