  org.directwebremoting.extend.DefaultJavascriptFunction

All Implemented Interfaces:

JavascriptFunction

public class DefaultJavascriptFunction
extends java.lang.Object
implements JavascriptFunction

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.
