Examples of URLImageCache

org.apache.batik.ext.awt.image.URLImageCache
This class manages a cache of soft references to Images that we have already loaded. Adding an image is two fold. First you add the ParsedURL, this lets the cache know that someone is working on this ParsedURL. Then when the completed RenderedImage is ready you put it into the cache.
If someone requests a ParsedURL after it has been added but before it has been put they will be blocked until the put.
