See GWT Exporter. This allows you to inject unobfuscated javascript
functions so you can call them through JSNI from the other module. If
you don't want to include exporter, all you have to do is inject the
functions through JSNI on module load. DISCLAIMER: this is untested,
you might have to modify to get it to work/compile.
public abstract class ModuleEntryPoint implements EntryPoint {
protected abstract String getModuleId();
public abstract void recieveData(String data);
public void onModuleLoad() {
injectCallback(this, getModuleId());
}
private native void injectCallback(ModuleEntryPoint instance,
String moduleId)/*-{
if ($wnd.moduleDataInterfaces == undefined)
$wnd.moduleDataInterfaces = [];
$wnd.moduleDataInterfaces[moduleId] = function(data) {
return
instan...@com.google.example.moduleentrypoint::recieveData(Ljava/lang/
String;)(data);
}
}-*/;
public static native void sendData(String moduleId, String data)/*-
{
if ($wnd.moduleDataInterfaces != undefined)
$wnd.moduleDataInterfaces[moduleId](data) ;
}-*/;
}
