Convert Event (or other) object to JSON in Widget API?

Question

In my custom widget I have created and gotten a hold of a reference to an Event object. My question is how can I marshall this to object into a JSON object. Is there something built in for this, or do I need to create my own marshaller of sorts with Velocity code? 
 And what about other object types (Thread, Wiki Page, etc.)? 
 And, if I needed to roll my own, are there any utilities in the widget API to properly escape string values as JSON? 
 Thanks.

There is not a built-in object-to-JSON serializer, instead, format the object using Velocity: 
 $core_v2_page.SetContentType('application/json')

{
 "Property":"$core_v2_encoding.JavascriptEncode($object.Property)",
 "Property2":"$core_v2_encoding.JavascriptEncode($object.Proeprty2)"
} 
 This allows you to include only the data you care about.
