How to Get Calendar Event global status? - google-apps-script

Question

This is concerning Google script to access Calendar event info
I'm looking for a method to get a Calendar Event global status? like for a Calendar Event with as status of attendess:
10 guests ==> 4 Yes, 3 MayBe, 1 No, 2 Awaiting
I've searched but I find only the way to get the status by guest, then implement a code to count individualy the global status.
Is there a way to get directly the global status?
Thanks in advance.

I happen to have written a function that does this. Here's an example of usage:
var summary = guestSummary(event.getGuestList());
Logger.log(summary);
...
[13-06-26 22:39:58:253 EDT] {respondedMaybe=0.0, awaiting=0.0, additional=0.0, respondedNo=0.0, respondedYes=1.0, invited=1.0}
I elected to use the guest list as a parameter, in order to support both CalendarEvent and CalendarEventSeries.
/**
* Return an object enumerating guest list summary information.
*
* #param {EventGuest[]} guestlist Array of EventGuests.
*
* #returns {object} guest list summary
*/
function guestSummary( guestlist ) {
var invited = guestlist.length;
var respondedYes = 0;
var respondedMaybe = 0;
var respondedNo = 0;
var awaiting = 0;
var additional = 0;
guestlist.forEach( function (guest) {
switch (guest.getGuestStatus()) {
case CalendarApp.GuestStatus.INVITED:
awaiting++;
break;
case CalendarApp.GuestStatus.YES:
respondedYes++;
break;
case CalendarApp.GuestStatus.NO:
respondedNo++;
break;
case CalendarApp.GuestStatus.MAYBE:
respondedMaybe++;
break;
default:
break;
}
additional += guest.getAdditionalGuests();
});
return {
invited : invited,
respondedYes : respondedYes,
respondedMaybe : respondedMaybe,
respondedNo : respondedNo,
awaiting : awaiting,
additional : additional
};
}
