org.sgx.yuigwt.yui.util.JsFunctionBuilder

sometimes java classes callbacks are not sufficient for representing a javascript function (for example in the Y.JSON.parse() with a reviver function). With this class is it possible to define javascript functions natively in javascript inline in java code like this:

 JsFunction reviver2 = new JsFunctionBuilder() {	 public native final JsFunction buildFunction()/*-{ return function(k, v) { if(k=="miscellaneous" && v>500) return 999999;  else return v;  } }-* /; }.buildFunction(); JsObject obj2 = Y.JSON().parse(jsonStr2, reviver2).cast();

        /*
         * Note: due to GWT types restrictions, we couldn't represent the JSON.parse() reviver function using a Java JsObject (function return value can be anything).
         * Instead se define a js function inline using JsFunctionBuilder.
         */
        JsFunction reviver2 = new JsFunctionBuilder() {
          @Override
          public native final JsFunction buildFunction()/*-{
            return function(k, v) {
              if (k == "miscellaneous" && v > 500)
                return 999999;

    
Widget button3 = Y.newButton(
  ButtonConfig.create().label("button3")
).render(parent);
//creating a native javascript function
JsFunction fn = new JsFunctionBuilder() {      
  @Override
  public native final JsFunction buildFunction()/*-{
    return function(e) {
      $wnd.alert("3 "+e.type+" at: "+e.domEvent.clientX); 
    }
