WhoisClient

public class FingerClient

extends SocketClient

The FingerClient class implements the client side of the Internet Finger Protocol defined in RFC 1288. To finger a host you create a FingerClient instance, connect to the host, query the host, and finally disconnect from the host. If the finger service you want to query is on a non-standard port, connect to the host at that port. Here's a sample use:

    FingerClient finger;
 
    finger = new FingerClient();

    try {
      finger.connect("foo.bar.com");
      System.out.println(finger.query("foobar", false));
      finger.disconnect();
    } catch(IOException e) {
      System.err.println("Error I/O exception: " + e.getMessage());
      return;
    }

Field Detail

DEFAULT_PORT

public static final int DEFAULT_PORT

The default FINGER port. Set to 79 according to RFC 1288.

Constructor Detail

FingerClient

public FingerClient()

The default FingerClient constructor. Initializes the default port to DEFAULT_PORT .

Method Detail

query

public java.lang.String query(boolean longOutput,
                              java.lang.String username)
                       throws java.io.IOException

Fingers a user at the connected host and returns the output as a String. You must first connect to a finger server before calling this method, and you should disconnect afterward.

Parameters:

longOutput - Set to true if long output is requested, false if not.

username - The name of the user to finger.

Returns:

The result of the finger query.

Throws:

java.io.IOException - If an I/O error occurs while reading the socket.

query

public java.lang.String query(boolean longOutput)
                       throws java.io.IOException

Fingers the connected host and returns the output as a String. You must first connect to a finger server before calling this method, and you should disconnect afterward. This is equivalent to calling query(longOutput, "") .

Parameters:

longOutput - Set to true if long output is requested, false if not.

Returns:

The result of the finger query.

Throws:

java.io.IOException - If an I/O error occurs while reading the socket.

getInputStream

public java.io.InputStream getInputStream(boolean longOutput,
                                          java.lang.String username)
                                   throws java.io.IOException

Fingers a user and returns the input stream from the network connection of the finger query. You must first connect to a finger server before calling this method, and you should disconnect after finishing reading the stream.

Parameters:

longOutput - Set to true if long output is requested, false if not.

username - The name of the user to finger.

Returns:

The InputStream of the network connection of the finger query. Can be read to obtain finger results.

Throws:

java.io.IOException - If an I/O error during the operation.

getInputStream

public java.io.InputStream getInputStream(boolean longOutput)
                                   throws java.io.IOException

Fingers the connected host and returns the input stream from the network connection of the finger query. This is equivalent to calling getInputStream(longOutput, ""). You must first connect to a finger server before calling this method, and you should disconnect after finishing reading the stream.

Parameters:

longOutput - Set to true if long output is requested, false if not.

Returns:

The InputStream of the network connection of the finger query. Can be read to obtain finger results.

Throws:

java.io.IOException - If an I/O error during the operation.
