Class CssHandler

java.lang.Object
  org.owasp.validator.css.CssHandler

All Implemented Interfaces:

org.w3c.css.sac.DocumentHandler

public class CssHandler
extends java.lang.Object
implements org.w3c.css.sac.DocumentHandler

A implementation of a SAC DocumentHandler for CSS validation. The appropriate validation method is called whenever the handler is invoked by the parser. The handler also builds a clean CSS document as the original CSS is scanned. NOTE: keeping state in this class is not ideal as handler style parsing a la SAX should generally be event driven. However, there is not a fully implemented "DOM" equivalent to CSS at this time. Java has a StyleSheet class that could accomplish this "DOM" like behavior but it has yet to be fully implemented.
