public class AgeFileFilter extends Object implements FileFilter, Serializable
For example, to print all files and directories in the current directory older than one day:
FileSystemManager fsManager = VFS.getManager(); FileObject dir = fsManager.toFileObject(new File(".")); // We are interested in files older than one day long cutoff = System.currentTimeMillis() - (24 * 60 * 60 * 1000); AgeFileFilter filter = new AgeFileFilter(cutoff); FileObject[] files = dir.findFiles(new FileFilterSelector(filter)); for (int i = 0; i < files.length; i++) { System.out.println(files[i]); }
