Thanks. Is there a tutorial on JavaScriptObject and JsArray somewhere
that you know of? I have already read the jsni chapter in "GWT in
Action" but still have trouble to understand how wrap java objects
and java collections.
In my particular case I have 3 methods (below). I guess that there is
no magic involved so that changing return type of getMapJs() to
JsArray<JavaScriptObject> would not work.
On the other hand, I tried printing out the return value of
$wnd.__getMapJs() and that turns to be a huge JavaScript Object and I
have no idea how to iterate through it. So an example will help
tremendously.
public Map<Long, GwtStock> getMap() {
return stockMap;
}
public native Map<Long, GwtStock> getMapJs() /*-{
return $wnd.__getMapJs();
}-*/;
public native void setUpJavaScriptApis(MapTest x) /*-{
$wnd.__getMapJs = function() {
return [email protected]::getMap()();
};
}-*/;
