Description

It would be useful to have a HomeDirectoryResolver interface to resolve a user's home directory. I use such a class to do the following:
1) Prefix a base path to user home directories. I have FtpServer deployed with two different applications. In one applicationI need their home directory to begin with "d:/mnt" and in the other I need "/mnt".
2) Allow users to share a common home directory (i.e. "d:/mnt/users").
3) Allow users to have private home directories (i.e. "d:/mnt/users/npadgett").

The interface I use looks something like:
<code>
public interface HomeDirectoryResolver {
String resolve(final User user);
}
</code>

The class I use looks something like:
<code>
public class HomeDirectoryResolverImpl implements HomeDirectoryResolver {
public static enum Strategy

{ SHARED, USERNAME, HOME_DIRECTORY }

private final String basePath;
private final Strategy strategy;

public HomeDirectoryResolverImpl(final String basePath,
final Strategy strategy)

{ this.basePath = basePath; this.strategy = strategy; }

public String resolve(final User user) {
String homeDirectory = this.basePath
+ (this.basePath.endsWith("/") ? "" : "/");
switch (this.strategy)

{ case SHARED: // do nothing break; case USERNAME: homeDirectory += user.getName(); break; case HOME_DIRECTORY: homeDirectory += user.getHomeDirectory(); break; default: throw new IllegalStateException(); }

return homeDirectory;
}
}
</code>
