These are |extern "C";|, and clients * should use |extern "C" {}| as appropriate when using this macro. * clasp: The JSClass for this object, or "dummy" if it doesn't exist. * * * Consumers wishing to iterate over all the JSProtoKey values, can use * JS_FOR_EACH_PROTOTYPE. However, there are certain values that don't * correspond to real constructors, like Null or constructors that are disabled * via preprocessor directives. We still need to include these in the JSProtoKey * list in order to maintain binary XDR compatibility, but we need to provide a * tool to handle them differently. JS_FOR_PROTOTYPES fills this niche. * * Consumers pass two macros to JS_FOR_PROTOTYPES - |REAL| and |IMAGINARY|. The * former is invoked for entries that have real client-exposed constructors, and * the latter is called for the rest. Consumers that don't care about this * distinction can simply pass the same macro to both, which is exactly what * JS_FOR_EACH_PROTOTYPE does. */ #define CLASP(NAME) (&NAME##Class) #define OCLASP(NAME) (&NAME##Object::class_) #define TYPED_ARRAY_CLASP(TYPE) (&TypedArrayObject::classes[Scalar::TYPE]) #define ERROR_CLASP(TYPE) (&ErrorObject::classes[TYPE]) #ifdef ENABLE_INTL_API #
