Class XNodeContextualDiffProvider

java.lang.Object
  org.ceryle.ui.xnode.XNodeContextualDiffProvider

All Implemented Interfaces:

XNodeDiffProvider

public class XNodeContextualDiffProvider
extends Object
implements XNodeDiffProvider

A diff provider which highlights changes word-by-word using CSS. This is based on the ContextualDiffProvider supplied with JSPWiki, and uses a private internal class, now a utility class called ChangeMerger. This handles diffs between XNode content, generating HTML (rather than XHTML) for use in Java Swing displays.

The colors used for display are set by setting System properties on ChangeMerger, not here.
