shouldn't you rename construct into something else and arg1 into reciever?

[podivilov, 2012/01/25 19:04:05]

I think construct is the right name, as we construct an Array in this method.
arg1 is first constructor argument, not reciever.

[Anton Muhin, 2012/01/26 12:13:35]

I think factory is ways better.

My understanding: constructor is method invoked on already allocated instance,
while factory both creates and initializes the object.  WDYT?

[podivilov, 2012/01/30 18:27:54]

Done.

         RefPtr<ArrayClass> array;
         if (Dart_IsNumber(arg1)) {
             ParameterAdapter<int> length(arg1);
             if (!length.conversionSuccessful()) {
                 exception = length.exception();
                 goto fail;
             }
             array = ArrayClass::create(length);
         } else {
             ParameterAdapter< Vector<ElementType> > list(arg1);
             if (!list.conversionSuccessful()) {
                 exception = list.exception();
                 goto fail;
             }
             array = ArrayClass::create(list->data(), list->size());
         }
         // FIXME: also process 3 argument constructor.
-        DartDOMWrapper::bindDOMObjectToDartWrapper(array.get(), Dart_GetNativeArgument(args, 0));
+        Dart_Handle result = toDartValue(array.get());
+        if (result)

care to add comment why you don't use ::returnValue here?
