#define BOOST_TTI_HAS_STATIC_MEMBER_DATA

(

name

)

Value:

BOOST_TTI_TRAIT_HAS_STATIC_MEMBER_DATA \
  ( \
  BOOST_TTI_HAS_STATIC_MEMBER_DATA_GEN(name), \
  name \
  ) \

Expands to a metafunction which tests whether a static member data with a particular name and type exists.

name = the name of the inner member.

generates a metafunction called "has_static_member_data_name" where 'name' is the macro parameter.

      The metafunction types and return:

        BOOST_TTI_TP_T    = the enclosing type.

        BOOST_TTI_TP_TYPE = the static member data type,
                   in the form of a data type,
                   in which to look for our 'name'.

        returns = 'value' is true if the 'name' exists,
                  with the appropriate BOOST_TTI_TP_TYPE type,
                  within the enclosing BOOST_TTI_TP_T type,
                  otherwise 'value' is false.

#define BOOST_TTI_TRAIT_HAS_STATIC_MEMBER_DATA	(		trait,
			name
	)

Value:

BOOST_TTI_DETAIL_TRAIT_HAS_STATIC_MEMBER_DATA(trait,name) \
  template<class BOOST_TTI_TP_T,class BOOST_TTI_TP_TYPE> \
  struct trait \
    { \
    typedef typename \
    BOOST_PP_CAT(trait,_detail_hsd)<BOOST_TTI_TP_T,BOOST_TTI_TP_TYPE>::type type; \
    BOOST_STATIC_CONSTANT(bool,value=type::value); \
    }; \

Expands to a metafunction which tests whether a static member data with a particular name and type exists.

trait = the name of the metafunction within the tti namespace.

name = the name of the inner member.

generates a metafunction called "trait" where 'trait' is the macro parameter.

      The metafunction types and return:

        BOOST_TTI_TP_T    = the enclosing type.

        BOOST_TTI_TP_TYPE = the static member data type,
                   in the form of a data type,
                   in which to look for our 'name'.

        returns = 'value' is true if the 'name' exists,
                  with the BOOST_TTI_TP_TYPE type,
                  within the enclosing BOOST_TTI_TP_T type,
                  otherwise 'value' is false.
