Resin Java Application Server
Resin's Virtual File System. Resin's VFS combines and simplifies the morass
in Java I/O. The core classes are:
Path
-- API similar to File, but supports URLs as well as
paths.
ReadStream
-- buffered read stream handing both
byte and character input
WriteStream
-- buffered write stream handling both
byte and character output
Virtual Paths
Path access is based on standard URLs. The following URL schemes are
predefined.
- file: -- the standard filesystem
- http: -- the http filesystem
- mailto: -- sending mail
- stdout: -- standard output (System.out)
- stderr: -- standard error (System.err)
- tcp: -- TCP socket pair
- null: -- /dev/null
- log: -- debug logging (controlled by resin.conf)
Reading a File
ReadStream
implements InputStream
so it can be
used wherever an InputStream
is appropriate.
The Vfs
facade is convenient for opening files.
ReadStream rs = Vfs.openRead("http://www.yahoo.com");
int ch;
while ((ch = rs.read()) >= 0)
System.out.print((char) ch);
Writing a File
WriteStream
implements OutputStream
so it can be
used wherever an OutputStream
is appropriate. It also implements
the familiar print()
methods from PrintStream
,
although they do throw IOExceptions.
The Vfs
facade is convenient for opening files.
WriteStream ws = Vfs.openWrite("mailto:[email protected]");
ws.setAttribute("subject", "hi, there");
ws.println("Just a little hello, world message");
ws.close();
