概述: 这些语法让你编写JavaScriptCore相关的绑定代码,本来这些绑定代码默认会被自动生成.
用法:
[ JSCustomToNativeObject, JSCustomFinalize, CustomIsReachable, JSCustomMarkFunction, JSCustomNamedGetterOnPrototype, JSCustomPushEventHandlerScope, JSCustomDefineOwnProperty, JSCustomDefineOwnPropertyOnPrototype, JSCustomGetOwnPropertySlotAndDescriptor ] interface XXX { };
你可以在这个文件里编写如下系列函数: WebCore/bindings/js/JSXXXCustom.cpp. 更多例子,请参考文件WebCore/bindings/js/JSXXXCustom.cpp
PassRefPtr<DOMWindow> toDOMWindow(JSGlobalData& globalData, JSValue value) { ...; }
void JSXXXOwner::finalize(JSC::Handle<JSC::Unknown> handle, void* context) { ...; }
bool JSXXXOwner::isReachableFromOpaqueRoots(JSC::Handle<JSC::Unknown> handle, void* context, SlotVisitor& visitor) { ...; }
void JSXXX::visitChildren(JSCell* cell, SlotVisitor& visitor) { ...; }
bool JSXXXPrototype::putDelegate(ExecState* exec, const Identifier& propertyName, JSValue value, PutPropertySlot& slot) { ...; }
ScopeChainNode* JSXXX::pushEventHandlerScope(ExecState* exec, ScopeChainNode* node) const { ...; }
bool JSXXX::defineOwnProperty(JSObject* object, ExecState* exec, const Identifier& propertyName, PropertyDescriptor& descriptor, bool throwException) { ...; }
bool JSXXXPrototype::defineOwnProperty(JSObject* object, ExecState* exec, const Identifier& propertyName, PropertyDescriptor& descriptor, bool throwException) { ...; }
bool JSXXX::getOwnPropertySlotDelegate(ExecState* exec, const Identifier& propertyName, PropertySlot& slot) { ...; } bool JSXXX::getOwnPropertyDescriptorDelegate(ExecState* exec, const Identifier& propertyName, PropertyDescriptor& descriptor) { ...; }
