Macro Definition Documentation

#define OWLCPP_NAMESPACE_TAG_TYPE	(		name,
			prefix_str,
			iri_str,
			i
	)

Value:

struct name { \
   typedef ::owlcpp::Ns_id id_type; \
   static const id_type::value_type index = i; \
   static std::string const & iri() { \
      static const std::string str=iri_str; \
      return str; \
   } \
   static std::string const & prefix() { \
      static const std::string str=prefix_str; \
      return str; \
   } \
   static id_type id() {return id_type(index);} \
}

Generate namespace IRI tag struct.

e.g.,

OWLCPP_NAMESPACE_TAG_TYPE(
   rdfs, "rdfs", "http://www.w3.org/2000/01/rdf-schema", 3
); 

expands to

 struct rdfs {
   static const unsigned index = 3;
   static std::string const & iri() {
      static const std::string str="http://www.w3.org/2000/01/rdf-schema";
      return str;
   }
   static std::string const & prefix() {
      static const std::string str="rdfs";
      return str;
   }
   typedef ::owlcpp::Ns_id id_type;
   static id_type id() {return id_type(index);}
};
