New subject: [boost-users][mpl, enable_if] checking if a type has specific dependant type

31 Dec 2008

      Hello,

I'd like to define a trait that would evaluate to true for types that
have some specific dependant type (DependentType), to use like this:
template<class Type> func(int i, typename
boost::enable_if::type* dummy = 0)
{
}

I tried this way:

template struct HasDependentType :
mpl::false_ {};
template<class Type> struct HasDependentType : mpl::true_ {};

...but it appears incorrect (partial specialization is never ised).

Thanks in advance.
