I am embedding V8 and I have the following javascript: var TSObject = (function (_super) { __extends(TSObject, _super); function TSObject() { return _super !== null && _super.apply(this, arguments) || this; } return TSObject; }(String));
As an embedder, I have registered the custom "__extends" function on the global object and my C++ callback is successfully invoked. My purpose is to be able to intercept the instantiation of such objects: var obj = new TSObject(); and to alter the type of js objects returned from the TSObject constructor (ideally by invoking some user provided C++ callback). Can such a hook be achieved from inside the "__extends" callback? The closest I could get is provide custom constructors for the base class but when the "_super.apply(this, arguments)" call is made, I am losing the information about TSObject and I only have access to the base class. Is there some way that I could walk the call frames and replace this constructor or reach the TSObject function so that I have information about this type? I can get the current callstack by using "v8::StackTrace::CurrentStackTrace" but this only gives me the function name as Local<String> and I cannot reach the actual Local<Function> from this frame. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
