check_no_pointers< T > Struct Template Reference

This class check if the type T has pointers inside. More...

Detailed Description

template<typename T>
struct check_no_pointers< T >

This class check if the type T has pointers inside.

It basically check if exist a function bool T::noPointers(), if not return UNKOWN if exist it return the noPointers return status

Template Parameters

T	type to check

Example

        struct test_no_ptr
        {
            static bool noPointers()    {return PNP::NO_POINTERS;}
        };
 
        struct test_ptr
        {
            static bool noPointers()    {return PNP::POINTERS;}
        };
 
        struct test_unknown
        {
        };
 
        int val = check_no_pointers<test_no_ptr>::value();
        BOOST_REQUIRE_EQUAL(val,PNP::NO_POINTERS);
        val = check_no_pointers<test_ptr>::value();
        BOOST_REQUIRE_EQUAL(val,PNP::POINTERS);
        val = check_no_pointers_impl<test_unknown,false>::value();
        BOOST_REQUIRE_EQUAL(val,PNP::UNKNOWN);
