Class File

java.lang.Object
  java.io.File
      org.apache.wicket.util.file.File

All Implemented Interfaces:

Serializable, Comparable<File>, IModifiable

Direct Known Subclasses:

Folder

public class File
extends File
implements IModifiable

Simple extension of File that adds an implementation of IModifiable for files. This allows the ModificationWatcher class to watch files for modification. The IModifiable.lastModifiedTime() method also returns a Time object with a more convenient API than either Date or a value in milliseconds.
