java.lang.Objectcom.caucho.vfs.Vfs
public final class Vfs
Facade to create useful Path and Stream objects.
The default scheme is the file scheme. Other schemes are
available using the full url.
For example, an application may want to set locale headers
for an HTTP request.
For example, on windows
Path path = Vfs.lookup("foo.html");
Path mail = Vfs.lookup("mailto:drofnats@foo.com.test?subject='hi'");
Stream body = mail.openWrite();
body.writeln("How's it going?");
body.close();
