Example #4

File: JSAPIWrapperObjectGLib.cpp Project: wolfviking0/webcl-webkit

{
    JSC::JSAPIWrapperObject* wrapperObject = JSC::jsCast<JSC::JSAPIWrapperObject*>(handle.get().asCell());
    // We use the JSGlobalObject when processing weak handles to prevent the situation where using
    // the same wrapped object in multiple global objects keeps all of the global objects alive.
    if (!wrapperObject->wrappedObject())
        return false;
    return JSC::Heap::isMarked(wrapperObject->structure()->globalObject()) && visitor.containsOpaqueRoot(wrapperObject->wrappedObject());
