Class TelnetAdapter

java.lang.Object

com.jscape.inet.telnet.TelnetAdapter

All Implemented Interfaces:

TelnetListener

Direct Known Subclasses:

TelnetTask

public class TelnetAdapter
extends java.lang.Object
implements TelnetListener

Implements methods for capturing events sourced from Telnet class. Typicaly your application will implement this interface to capture the following events :

TelnetConnectedEvent
TelnetDisconnectedEvent
DoOptionEvent
DontOptionEvent
WillOptionEvent
WontOptionEvent
DoSubOptionEvent
TelnetDataReceivedEvent

In addition to extending this class your application should register itself as an EventListener which may look somewhat like this:

 public class Application ... extends TelnetAdapter
 {
  ...
  public ... initMethod(...)
  {
    Telnet telnet = new Telnet("myserver.com");
    telnet.addTelnetListener(this);
  }
  ...
 }
