Serializable, CharTransformer, ConfigurableTransformer, Transformer

public class LinkFinder
extends RegexpReplacer

Finds links in the Character String, and makes them 'clickable' for HTML (using a-tags). This implementation is very simple and straightforward. It contains a list of regular expression which are matched on all 'words'. It ignores existing XML markup, and also avoids trailing dots and comments and surrounding quotes and parentheses.
