NaiveUserAgent is a simple implementation of {@link org.xhtmlrenderer.extend.UserAgentCallback} which places no restrictions on whatXML, CSS or images are loaded, and reports visited links without any filtering. The most straightforward process available in the JDK is used to load the resources in question--either using java.io or java.net classes.
The NaiveUserAgent has a small cache for images, the size of which (number of images) can be passed as a constructor argument. There is no automatic cleaning of the cache; call {@link #shrinkImageCache()} to remove the least-accessed elements--for example, you might do thiswhen a new document is about to be loaded. The NaiveUserAgent is also a DocumentListener; if registered with a source of document events (like the panel hierarchy), it will respond to the {@link org.xhtmlrenderer.event.DocumentListener#documentStarted()} call and attempt to shrink its cache.
This class is meant as a starting point--it will work out of the box, but you should really implement your own, tuned to your application's needs. @author Torbjoern Gannholm
