TelnetClient (NetComponents 1.3.8 API)

java.lang.Object
- com.oroinc.net.SocketClient
- - com.oroinc.net.telnet.TelnetClient

Direct Known Subclasses:

FTP
```
public class TelnetClient
extends SocketClient
```
The TelnetClient class implements the simple network virtual terminal (NVT) for the Telnet protocol according to RFC 854. It does not implement any of the extra Telnet options because it is meant to be used within a Java program providing automated access to Telnet accessible resources. A telnet client implementing extra options and meant for use with a terminal emulator can be found in NetComponents Pro ^TM
The class can be used by first connecting to a server using the SocketClient connect method. Then an InputStream and OutputStream for sending and receiving data over the Telnet connection can be obtained by using the getInputStream() and getOutputStream() methods. When you finish using the streams, you must call disconnect rather than simply closing the streams.

- Constructor Detail
  - TelnetClient
```
public TelnetClient()
```
    Default TelnetClient constructor.
- Method Detail
  - _connectAction_
```
protected void _connectAction_()
                        throws java.io.IOException
```
    Handles special connection requirements.
    
    Throws:
    
    java.io.IOException - If an error occurs during connection setup.
  - disconnect
```
public void disconnect()
                throws java.io.IOException
```
    Disconnects the telnet session, closing the input and output streams as well as the socket. If you have references to the input and output streams of the telnet connection, you should not close them yourself, but rather call disconnect to properly close the connection.
    
    Overrides:
    
    disconnect in class SocketClient
    
    Throws:
    
    java.io.IOException - If there is an error closing the socket.
  - getOutputStream
```
public java.io.OutputStream getOutputStream()
```
    Returns the telnet connection output stream. You should not close the stream when you finish with it. Rather, you should call disconnect .
    
    Returns:
    
    The telnet connection output stream.
  - getInputStream
```
public java.io.InputStream getInputStream()
```
    Returns the telnet connection input stream. You should not close the stream when you finish with it. Rather, you should call disconnect .
    
    Returns:
    
    The telnet connection input stream.
