public class JavaScriptObject
extends java.lang.Object

An opaque handle to a native JavaScript object. A JavaScriptObject cannot be created directly. JavaScriptObject should be declared as the return type of a JSNI method that returns native (non-Java) objects. A JavaScriptObject passed back into JSNI from Java becomes the original object, and can be accessed in JavaScript as expected.

SUBCLASSING IS NOT SUPPORTED EXCEPT FOR THE EXISTING SUBCLASSES.
