public interface EFile
- extends Entity, ReadWritableFile, NamedReadableFile
This is an interface for a file implementation. A file supports being read
and written to.
Physical file system-backed file system implementations support the
FCFileBacked capability. It allows the
client to open FileInputStream:s and FileOutputStream:s on
the file, and use it as an RandomAccessFile.
In addition to the methods defined in this interface, the class
Files contains static utility methods for working
with files.
A file is Observable for updates. It can send the following events:
EntityDeletedEvent — the file was deleted.EntityModifiedEvent — the file was modified in a way that
updated its last modification time (see EntityView.getLastModified()
). If a client is writing to a file, this event is only fired when the
client's output stream is closed, not every time that it writes to the file.EntityRenamedEvent — the file was renamed and/or moved.NewEntityEvent — the file was created. This event can only
be received from a file system observer since it is sent before a client can
register an observer on the file. (Unless the event manager is paused; see
the developer documentation for more on that.)
