Class DebugFrameImpl

java.lang.Object

      com.gargoylesoftware.htmlunit.javascript.DebugFrameImpl

All Implemented Interfaces:

net.sourceforge.htmlunit.corejs.javascript.debug.DebugFrame

public class DebugFrameImpl
extends DebugFrameAdapter

HtmlUnit's implementation of the DebugFrame interface, which logs stack entries as well as exceptions. All logging is done at the TRACE level. This class does a fairly good job of guessing names for anonymous functions when they are referenced by name from an existing object. See the Rhino documentation or the interface source code for more information on the DebugFrame interface and its uses.

Please note that this class is intended mainly to aid in the debugging and development of HtmlUnit itself, rather than the debugging and development of web applications.
