Class DefaultJavascriptObject

All Implemented Interfaces:

java.lang.reflect.InvocationHandler, JavascriptObject

public class DefaultJavascriptObject
extends java.lang.Object
implements JavascriptObject, java.lang.reflect.InvocationHandler

Represents a callback function, passed in from a client for later execution.

A DefaultJavascriptFunction is tied to a specific function in a specific browser page. In this way the eval of a DefaultJavascriptFunction is outside of the normal execution scoping provided by Browser.
