[Jscustomtonativeobject](i),[Jscustomfinalize](i),[customisreachable](i),[Jscustommarkfunction](i),[Jscustomnamedgetteronprototype](i),[Jscustompusheventhandlerscope](i),[Jscustomdefineownproperty](i),[Jscustomdefineownpropertyonprototype](i),[Jscustomgetownpropertyslotanddescriptor](i)

Overview: These syntaxes allow you to write JavaScriptCore-related binding code that would otherwise be automatically generated by default.

Usage:

    [        Jscustomtonativeobject,        jscustomfinalize,        customisreachable,        jscustommarkfunction,        Jscustomnamedgetteronprototype,        Jscustompusheventhandlerscope,        Jscustomdefineownproperty,        Jscustomdefineownpropertyonprototype,        jscustomgetownpropertyslotanddescriptor    ] interface XXX {    };

You can write the following series of functions in this file: Webcore/bindings/js/jsxxxcustom.cpp. For more examples, please refer to document Webcore/bindings/js/jsxxxcustom.cpp

• [Jscustomtonativeobject]: For example, you can write your own Todomwindow (...):

    Passrefptr<domwindow> Todomwindow (jsglobaldata& globalData, jsvalue value)    {        ...;    }

• [Jscustomfinalize]: Define your own 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 own jsxxx::visitchildren (...) function :

    void Jsxxx::visitchildren (jscell* cell, slotvisitor& visitor)    {        ...;    }

• [ Jscustomnamedgetteronprototype] : define your own   jsxxxprototype::p utdelegate (...) function :

    BOOL Jsxxxprototype::p utdelegate (execstate* exec, const identifier& propertyname, Jsvalue value, Putpropertyslot & slots)    {        ...;    }

• [Jscustompusheventhandlerscope]: define your own jsxxx::p usheventhandlerscope (...) function :

    scopechainnode* jsxxx::p usheventhandlerscope (execstate* exec, scopechainnode* node) const    {        ...;    }

• [Jscustomdefineownproperty]: define your own jsxxx::d efineownproperty (...) function :

    BOOL Jsxxx::d efineownproperty (jsobject* object, execstate* exec, const identifier& PropertyName, propertydescriptor& descriptor, bool throwexception)    {        ...;    }

• [Jscustomdefineownpropertyonprototype]: define your own prototype properties jsxxxprototype:: Defineownproperty (...):

    BOOL Jsxxxprototype::d efineownproperty (jsobject* object, execstate* exec, const identifier& PropertyName, propertydescriptor& descriptor, bool throwexception)    {        ...;    }

• [Jscustomgetownpropertyslotanddescriptor]: define your own jsxxx::getownpropertyslotdelegate (...) and jsxxx::getownpropertydescriptordelegate (...) function :

    BOOL Jsxxx::getownpropertyslotdelegate (execstate* exec, const identifier& PropertyName, propertyslot& slots)    {        ...;    }    BOOL Jsxxx::getownpropertydescriptordelegate (execstate* exec, const identifier& PropertyName, PropertyDescriptor & descriptor)    {        ...;    }
