java.lang.Objectnet.didion.jwnl.dictionary.file_manager.FileManagerImpl
net.didion.jwnl.dictionary.file_manager.RemoteFileManager
public class RemoteFileManager
An object of this class can serve as a FileManager for remote FileBackedDictionary
instantiations using RMI. This class also contains utility routines to publish a RemoteFileManager
for remote use, and to lookup a remote one for local use.
To make a RemoteFileManager available to remote clients:
System.setSecurityManager(new RMISecurityManager()); LocateRegistry.createRegistry(Registry.REGISTRY_PORT); new RemoteFileManager().bind();
To create a local Dictionary backed by a remote RemoteFileManager:
Dictionary dictionary = new FileBackedDictionary(RemoteFileManager.lookup(hostname));
