Re: Passing Object Literal to Javascript method ?

I would build it like:

Mutable version:

class Options extends JavaScriptObject {

   public native Options with(String option, String value) /*-{

      this[option] = value;

      return this;

   }-*/;

}

Options options = Options.createObject()

    .with("opacity", "0.5")

    .with("width", "100");

An immutable Options class would also be possible but as it is GWT you are dealing with things are never really immutable thanks to JSNI magic. Using JSNI magic you could hide the JavaScriptObject from Java code but still use it inside your perform() method, e.g.

class Options {

   private JavaScriptObject nativePeer;

   // Builder class having the "with(.., ..)" method and which configures the native peer

   // getter, etc. to inspect the native peer if needed.

}

public native CssHolder perform(Element e, int duration, Options options) /*-{

   var nativeOptions = options.@<full qualified class name>::nativePeer;

   return $wnd.CssMod.perform(e, duration, nativeOptions);

}-*/;
