Hi all,
I have recently started testing JsInterop for our GWT 2.8.1 application and
I have encountered a situation I could not solve without using the old
style JSNI approach.
Consider the following minimal JS library I would like to use in Java/GWT:
(function (window, document, undefined) {
function WatchDog(name) {
this._name = name;
};
WatchDog.prototype.register = function(callback) {
this._callback = callback;
};
WatchDog.prototype.broadcast = function(msg) {
if (this._callback) {
this._callback({
'name' : this._name,
'timestamp' : new Date().getTime(),
'msg' : msg
});
}
};
window.Dummy = {
watchDog : function(name) {
return new WatchDog(name);
}
};
}(window, document));
Please note that the broadcast function passes a "basic" JS Object {} (i.e.
without a specific prototype) to the callback function.
Here below my JsInterop mappings:
package xxx;
import jsinterop.annotations.JsPackage;
import jsinterop.annotations.JsType;
@JsType(isNative = true, namespace = JsPackage.GLOBAL)
public class Dummy {
private Dummy() {}
public static native WatchDog watchDog(String name);
}
package xxx;
import jsinterop.annotations.JsMethod;
import jsinterop.annotations.JsType;
@JsType(isNative = true)
public class WatchDog {
private WatchDog() {}
@JsMethod
public native void register(Callback callback);
@JsMethod
public native void broadcast(String msg);
}
package xxx;
import jsinterop.annotations.JsFunction;
@JsFunction
public interface Callback {
void call(Object event);
}
In my Java code, when the callback function is invoked, the event parameter
is an instance of com.google.gwt.core.client.JavaScriptObject.
Without using JSNI I am not able to access/read the object's properties.
Does JsInterop addresses this scenario without falling-back to old style
JSNI?
Thanks a lot in andvance
Andrea
