/**
 * <p>
 * A FileOperation is an object that brings an extra functions to a FileObject.
 * The VFS provides the basic functionality to deal with FileObject's. Tha is
 * create, delete, rename, copy, etc functions. However, if you are working with
 * FileSystem and its files are, for example, under Version Control System (VCS)
 * you might want to get an access to the versioning framework and to be able to
 * manage your files regarding VCS (e.g. commit them, undate, get logs, etc.).
 * Such type of extended functionality is provided by FileOperation.
 * </p>
 * <p>
 * The FileOperation interface is a genetic interface that should not be
 * implemented directly. It rather should be extended by other interfaces that
 * provide some concrete functions.
 * </p>
 * <p>
 * FileOperation is provided by
 * 
 * @see FileOperationProvider Especially the FileOperationProvider is responsible
 *      for looking up and instantiating any concrete FileOperation.
