Re: webidl, jsinterop and overloaded methods

I found the well writen spec from Goktug Gokdogan (https://docs.google.com/document/d/1tir74SB-ZWrs-gQ8w-lOEV3oMY6u6lF2MmNivDEihZ4/edit?usp=sharing)

It clarifies that method overloading only is a problem if you have a Java implementation with overloaded methods and you want to call it from Javascript.

I am only consuming JS objects from Java which does not have the problem, so that is why it works fine after I disabled the check in GWT.

Hi

Thank you. For now I continue running a hacked version of GWT for my toy project. It simply disables the check and everything seems to work fine for the scenarios that I have tried out. There must be some special case where it does not work since they have disabled it, but I have not hit any of those yet.

  You can see in this thread a discussion of method overloading, and the proposed support for next release of GWT.

Hi

I am toying around with generating Java interfaces annotated with @JsType and @JsProperty from webidl. But I have a problem with overloaded methods.

For example: The idl for CanvasRenderingContext2 has several overloaded methods

fx

  void stroke();
  void stroke(Path2D path);

and

  ImageData createImageData(double sw, double sh);
  ImageData createImageData(ImageData imagedata);

I can generate a corresponding Java interface with the overloaded methods, but the GWT compiler fails with this

Error:(75, 0) GWT Compiler: JsType methods cannot overload another method.

I know JS does not support function overloading as such, but on the other hand, you can pass anything to a js function regardless of the specified parameters.

Do you have any ideas for how I can resolve these issues?
