<p>name = the name of the inner member.</p>
<p>generates a metafunction called "has_static_member_function_name" where 'name' is the macro parameter. template<class BOOST_TTI_TP_T,class BOOST_TTI_TP_R,class BOOST_TTI_TP_FS,class BOOST_TTI_TP_TAG>
struct trait
{
static const value = unspecified;
typedef mpl::bool_<true-or-false> type;
};
The metafunction types and return:
BOOST_TTI_TP_T = the enclosing type in which to look for our 'name'.
BOOST_TTI_TP_R = the return type of the static member function
OR
the signature of a function in the form of Return_Type ( Parameter_Types )
BOOST_TTI_TP_FS = (optional) the parameters of the static member function as a boost::mpl forward sequence
if the second parameter is a return type and the function parameters exist.
BOOST_TTI_TP_TAG = (optional) a boost::function_types tag to apply to the static member function
if the second parameter is a return type and the need for a tag exists.
returns = 'value' is true if the 'name' exists,
with the appropriate static member function type,
otherwise 'value' is false. </p>
