Member Function Documentation

template<typename Type >

template<typename U >

static No& SUNphi::HasMember_ref2< Type >::test ( Check< int Fallback::*,&U::ref2 > *  )

static

Forward definition of test function, taking a pointer to the

type of ref2 as argument, returning No. The instantiation

will fail if Base have two member ref2 implemented, which

means that Type has the member

template<typename Type >

template<typename U >

static Yes& SUNphi::HasMember_ref2< Type >::test (   ... )

static

Forward definition of test function, taking a pointer to the

type of ref2 as argument, returning Yes. The instantiation

will work when the other fails, which means that Type does

have the member

Member Data Documentation

template<typename Type >

constexpr bool SUNphi::HasMember_ref2< Type >::result = sizeof(test<Derived>(nullptr))==sizeof(Yes)

static

Result of the check, comparing the size of return type of

test with the size of yes
