There are part of the XDR API, and must not change. michael@0: * init: Initialization function. These are |extern "C";|, and clients should use michael@0: * |extern "C" {}| as appropriate when using this macro. michael@0: * clasp: The JSClass for this object, or "dummy" if it doesn't exist. michael@0: * michael@0: * michael@0: * Consumers wishing to iterate over all the JSProtoKey values, can use michael@0: * JS_FOR_EACH_PROTOTYPE. However, there are certain values that don't correspond michael@0: * to real constructors, like Null or constructors that are disabled via michael@0: * preprocessor directives. We still need to include these in the JSProtoKey list michael@0: * in order to maintain binary XDR compatibility, but we need to provide a tool michael@0: * to handle them differently. JS_FOR_PROTOTYPES fills this niche. michael@0: * michael@0: * Consumers pass two macros to JS_FOR_PROTOTYPES - |real| and |imaginary|. The michael@0: * former is invoked for entries that have real client-exposed constructors, and michael@0: * the latter is called for the rest. Consumers that don't care about this michael@0: * distinction can simply pass the same macro to both, which is exactly what michael@0: * JS_FOR_EACH_PROTOTYPE does. michael@0: */ michael@0: michael@0: #define CLASP(name) (&name##Class) michael@0: #define OCLASP(name) (&name##Object::class_) michael@0: #define TYPED_ARRAY_CLASP(type) (&TypedArrayObject::classes[ScalarTypeDescr::type]) michael@0: michael@0: #ifdef ENABLE_PARALLEL_JS michael@0: #define IF_PJS(real,imaginary) real michael@0: #else michael@0: #define IF_PJS(real,imaginary) imaginary michael@0: #endif michael@0: michael@0: #ifdef EXPOSE_INTL_API michael@0: #define IF_INTL(real,imaginary) real michael@0: #else michael@0: #define IF_INTL(real,imaginary) imaginary michael@0: #endif michael@0: michael@0: #ifdef ENABLE_BINARYDATA michael@0: #define IF_BDATA(real,imaginary) real michael@0: #else michael@0: #define IF_BDATA(real,imaginary) imaginary michael@0: #endif michael@0: michael@0: #ifdef ENABLE_SHARED_ARRAY_BUFFER michael@0: #define IF_SAB(real,imaginary) real michael@0: #else michael@0: #define IF_SAB(real,imaginary) imaginary michael@0: #endif michael@0: michael@0: #define JS_FOR_PROTOTYPES(real,imaginary) \ michael@0: imaginary(Null, 0, js_InitNullClass, dummy) \ michael@0: real(Object, 1, js_InitObjectClass, &JSObject::class_) \ michael@0: real(Function, 2, js_InitFunctionClass, &JSFunction::class_) \ michael@0: real(Array, 3, js_InitArrayClass, OCLASP(Array)) \ michael@0: real(Boolean, 4, js_InitBooleanClass, OCLASP(Boolean)) \ michael@0: real(JSON, 5, js_InitJSONClass, CLASP(JSON)) \ michael@0: real(Date, 6, js_InitViaClassSpec, OCLASP(Date)) \ michael@0: real(Math, 7, js_InitMathClass, CLASP(Math)) \ michael@0: real(Number, 8, js_InitNumberClass, OCLASP(Number)) \ michael@0: real(String, 9, js_InitStringClass, OCLASP(String)) \ michael@0: real(RegExp, 10, js_InitRegExpClass, OCLASP(RegExp)) \ michael@0: real(Error, 11, js_InitExceptionClasses, OCLASP(Error)) \ michael@0: real(InternalError, 12, js_InitExceptionClasses, OCLASP(Error)) \ michael@0: real(EvalError, 13, js_InitExceptionClasses, OCLASP(Error)) \ michael@0: real(RangeError, 14, js_InitExceptionClasses, OCLASP(Error)) \ michael@0: real(ReferenceError, 15, js_InitExceptionClasses, OCLASP(Error)) \ michael@0: real(SyntaxError, 16, js_InitExceptionClasses, OCLASP(Error)) \ michael@0: real(TypeError, 17, js_InitExceptionClasses, OCLASP(Error)) \ michael@0: real(URIError, 18, js_InitExceptionClasses, OCLASP(Error)) \ michael@0: real(Iterator, 19, js_InitIteratorClasses, OCLASP(PropertyIterator)) \ michael@0: real(StopIteration, 20, js_InitIteratorClasses, OCLASP(StopIteration)) \ michael@0: real(ArrayBuffer, 21, js_InitTypedArrayClasses, &js::ArrayBufferObject::protoClass) \ michael@0: real(Int8Array, 22, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_INT8)) \ michael@0: real(Uint8Array, 23, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_UINT8)) \ michael@0: real(Int16Array, 24, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_INT16)) \ michael@0: real(Uint16Array, 25, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_UINT16)) \ michael@0: real(Int32Array, 26, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_INT32)) \ michael@0: real(Uint32Array, 27, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_UINT32)) \ michael@0: real(Float32Array, 28, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_FLOAT32)) \ michael@0: real(Float64Array, 29, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_FLOAT64)) \ michael@0: real(Uint8ClampedArray, 30, js_InitTypedArrayClasses, TYPED_ARRAY_CLASP(TYPE_UINT8_CLAMPED)) \ michael@0: real(Proxy, 31, js_InitProxyClass, &ProxyObject::uncallableClass_) \ michael@0: real(WeakMap, 32, js_InitWeakMapClass, OCLASP(WeakMap)) \ michael@0: real(Map, 33, js_InitMapClass, OCLASP(Map)) \ michael@0: real(Set, 34, js_InitSetClass, OCLASP(Set)) \ michael@0: real(DataView, 35, js_InitTypedArrayClasses, OCLASP(DataView)) \ michael@0: IF_SAB(real,imaginary)(SharedArrayBuffer, 36, js_InitSharedArrayBufferClass, &js::SharedArrayBufferObject::protoClass) \ michael@0: IF_INTL(real,imaginary) (Intl, 37, js_InitIntlClass, CLASP(Intl)) \ michael@0: IF_BDATA(real,imaginary)(TypedObject, 38, js_InitTypedObjectModuleObject, OCLASP(TypedObjectModule)) \ michael@0: imaginary(GeneratorFunction, 39, js_InitIteratorClasses, dummy) \ michael@0: IF_BDATA(real,imaginary)(SIMD, 40, js_InitSIMDClass, OCLASP(SIMD)) \ michael@0: michael@0: #define JS_FOR_EACH_PROTOTYPE(macro) JS_FOR_PROTOTYPES(macro,macro) michael@0: michael@0: #endif /* jsprototypes_h */
