Field Summary

protected List<FileServer>	mFileServers The list of file servers that can be used to write to access this directory.
protected InternalMountPoint	mInternalMount The internal mount point for the directory.

Constructor Summary

DirectoryType()
The default constructor.

DirectoryType(List<FileServer> fs, InternalMountPoint imt)
The overloaded constructor

Method Summary

void	addFileServer(FileServer server) Adds a FileServer that can access this directory.
Object	clone() Returns the clone of the object.
Iterator<FileServer>	getFileServersIterator() Returns at iterator to the file servers.
InternalMountPoint	getInternalMountPoint() Returns the internal mount point for the directory.
void	initialize() Initializes the object
void	initialize(List<FileServer> fs, InternalMountPoint imt) Initializes the object
boolean	isEmpty() A convenience method that returns true if all the attributes values are uninitialized or empty strings.
FileServer	selectFileServer() Selects a random file server and returns it.
void	setFileServers(List<FileServer> servers) Sets the list of FileServers that can access this directory.
