Cannot find any developer information about this function. I just know that it's suggested to wrap JSNI JavaScript calls to Java methods with this $entry function. I found that it catches exceptions so Java code could handle them. Is it all it does?

If you want to know exactly what happens, look into com.google.gwt.core.client.impl.Impl.entry(JavaScriptObject jsFunction).

This function (at least in GWT 2.2.0) mainly calls entry0(Object jsFunction, Object thisObj, Object arguments), which does the following:

  • First, it flushes anything that has been scheduled by Scheduler.scheduleEntry()
  • Then it makes sure to execute the jsFunction in a try block, to forward Exceptions to GWT.getUncaughtExceptionHandler(), if there is such a handler.
  • Finally, it flushes anything that has been scheduled by Scheduler.scheduleFinally()
