<p> MMBase Utils is a part of MMBase, but can also be used in other projects. It contains several kind of utility classes.</p> <p>Highlights:</p> <ul> <li>An implementation of 'events'. Threads can use this to communicate certain things. Using mmbase-clustering, these events can also be sent to other servers.</li> <li>A logging framework</li> <li>A framework for string and byte array transformeration, plus a whole lot of implemetentations for that.</li> <li>Several java.util like classes (collections, dateparsing)</li> <li>File type recognition ('magicfile')</li> <li>The MMBase resourceloader, a generic fall-back mechanism for configuration files and similar resources.</li> <li>...</li> </ul>
