#define BOOST_TTI_HAS_MEMBER_DATA | ( | name | ) |
Expands to a metafunction which tests whether a member data with a particular name and type exists.
name = the name of the inner member.
generates a metafunction called "has_member_data_name" where 'name' is the macro parameter.

BOOST_TTI_TP_TYPE = (optional) The type of the member data if the first parameter is the enclosing type. returns = 'value' is true if the 'name' exists, with the correct data type, otherwise 'value' is false.

Expands to a metafunction which tests whether a member data with a particular name and type exists.
trait = the name of the metafunction.
name = the name of the inner member to introspect.
generates a metafunction called "trait" where 'trait' is the macro parameter.
