- public class WordFilter
- extends Hash
- implements Filter
This filter uses StringTokenizer to create "words" and allow
you to replace on those "words". A word is defined as anything
between two spaces. This filter should be relatively fast and
shows how easy it is to implement your own filters.
Filter filter = new WordFilter();
filter.addAttribute("there","where");
filter.addAttribute("it","is");
filter.addAttribute("goes","it");
P p = new P();
p.setFilter(filter);
p.addElement("there it goes");
System.out.println(p.toString());
Produces: <p>where is it
