Summary: These syntaxes allow you to write JavaScriptCore-related binding code, which will be automatically generated by default.

Usage:

    [        JSCustomToNativeObject,        JSCustomFinalize,        CustomIsReachable,        JSCustomMarkFunction,        JSCustomNamedGetterOnPrototype,        JSCustomPushEventHandlerScope,        JSCustomDefineOwnProperty,        JSCustomDefineOwnPropertyOnPrototype,        JSCustomGetOwnPropertySlotAndDescriptor    ] interface XXX {    };

You can compile the following series of functions in this file: WebCore/bindings/js/JSXXXCustom. cpp. For more examples, see the file WebCore/bindings/js/JSXXXCustom. cpp.

• [JSCustomToNativeObject]For example, you can write your ownToDOMWindow (...):

    PassRefPtr<DOMWindow> toDOMWindow(JSGlobalData& globalData, JSValue value)    {        ...;    }

• [JSCustomFinalize]: Define Your finalize function:

    void JSXXXOwner::finalize(JSC::Handle<JSC::Unknown> handle, void* context)    {        ...;    }

• [CustomIsReachable]: Define your own isReachableFromOpaqueRoots function:

    bool JSXXXOwner::isReachableFromOpaqueRoots(JSC::Handle<JSC::Unknown> handle, void* context, SlotVisitor& visitor)    {        ...;    }

• [JSCustomMarkFunction]: Define your ownJSXXX: visitChildren (...)Function:

    void JSXXX::visitChildren(JSCell* cell, SlotVisitor& visitor)    {        ...;    }

• [JSCustomNamedGetterOnPrototype]: Define your ownJSXXXPrototype: putDelegate (...)Function:

    bool JSXXXPrototype::putDelegate(ExecState* exec, const Identifier& propertyName, JSValue value, PutPropertySlot& slot)    {        ...;    }

• [JSCustomPushEventHandlerScope]: Define your ownJSXXX: pushEventHandlerScope (...)Function:

    ScopeChainNode* JSXXX::pushEventHandlerScope(ExecState* exec, ScopeChainNode* node) const    {        ...;    }

• [JSCustomDefineOwnProperty]: Define your ownJSXXX: defineOwnProperty (...)Function:

    bool JSXXX::defineOwnProperty(JSObject* object, ExecState* exec, const Identifier& propertyName, PropertyDescriptor& descriptor, bool throwException)    {        ...;    }

• [JSCustomDefineOwnPropertyOnPrototype]: Define your own prototype attributesJSXXXPrototype: defineOwnProperty (...):

    bool JSXXXPrototype::defineOwnProperty(JSObject* object, ExecState* exec, const Identifier& propertyName, PropertyDescriptor& descriptor, bool throwException)    {        ...;    }

• [JSCustomGetOwnPropertySlotAndDescriptor]: Define your ownJSXXX: getOwnPropertySlotDelegate (...)AndJSXXX: getOwnPropertyDescriptorDelegate (...) Function:

    bool JSXXX::getOwnPropertySlotDelegate(ExecState* exec, const Identifier& propertyName, PropertySlot& slot)    {        ...;    }    bool JSXXX::getOwnPropertyDescriptorDelegate(ExecState* exec, const Identifier& propertyName, PropertyDescriptor& descriptor)    {        ...;    }
