public class FileCache
- extends java.lang.Object
The file area cache used by the image code. This maintains the file cache and cleans it out every
once in a while. To ensure safe access all files in the cache must be retrieved through
this file cache, and after use these need to be released. This ensures that no files are removed
that are currently in use.
