Hello there, So, when working on a javascript binding engine we faced the following problem: How to create a JSObjectRef as the same type as another one.
With SpiderMonkey, we could use JS_GetClass to get the JSObject's class, and then use that JSClass to build the new object. There's no such API on JavaScriptCore. I'd heard some suggestions to workaround the issue with Set/Get privates or prototypes, but it definitely didn't get the expected result. So, I know the JSObjectRef API has been stable for a while, but I would like to propose the inclusion of the following API in the public list of jsc APIs. * JSClassRef JSObjectGetClass(JSObjectRef obj). I can see this API being used for: * Knowing if two objects are from the same class (by using JSValueIsObjectOfClass) * Creating dynamic constructors using another JSObjectRef as reference for the class. I did submit a bug and a patch for it: https://bugs.webkit.org/show_bug.cgi?id=160032 Would be lovely if a JSC engineer could drop some thoughts or maybe a review there... Thanks, Danilo Cesar Lemes de Paula _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev
