Listening for events
Top  Previous  Next

For an object to listen for events published by the IpClient class the following steps are required:

1. Set object to implement
IpClientListener
2. Overload event handling methods.
3. Subscribe object to receive events published by
IpClient instance.

Example


The example below demonstrates using the
IpClientListener class.

import com.jscape.inet.ipclient.*;
import java.io.*;

public class MyIpClientListener implements IpClientListener {

   public void connected(IpClientConnectedEvent event) {
      System.out.println("Connected to host: "
 + event.getHostname());
   }

   public void disconnected(IpClientDisconnectedEvent event) {
      System.out.println("Disconnected from host: "
 + event.getHostname());
   }
   
   public static void main(String[] args) {
      try {
         // create new IpClient instance

         IpClient client = new IpClient("www.yahoo.com"
,80);
         
         // subscribe listener

         client.addIpClientListener(new MyIpClientListener());
         
         // establish connection

         client.connect();
         
         // get output stream

         OutputStream out = client.getOutputStream();
         
         // send data

         String command = "GET / HTTP/1.0\r\n\r\n"
;
         out.write(command.getBytes());
         out.flush();
         
         // get input stream

         InputStream in = client.getInputStream();
               
         // read data from server

         int i = 0
;
         while((i = in.read()) != -1
) {
            System.out.print((char)i);
         }      
         
         // disconnect

         client.disconnect();
         
      } catch(Exception e) {
         e.printStackTrace();
      }
   }
   

}
