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 EXPOSE_INTL_API #define IF_INTL(real,imaginary) real #else #define IF_INTL(real,imaginary) imaginary #endif #ifdef ENABLE_BINARYDATA #define IF_BDATA(real,imaginary) real #else #define IF_BDATA(real,imaginary) imaginary #endif #ifdef ENABLE_SIMD #
