Examples of QuickServer

org.quickserver.net.server.QuickServer
Main class of QuickServer library. This class is used to create multi client servers quickly.
Ones a client is connected, it creates {@link ClientHandler} object, which is run using any thread available from the pool of threads maintained by {@link org.quickserver.util.pool.thread.ClientPool}, which handles the client.
QuickServer divides the application logic of its developer over eight class,
- ClientEventHandler
  Handles client events [Optional Class].
- ClientCommandHandler [#]
  Handles client character/string commands.
- ClientObjectHandler [#]
  Handles client interaction - Object commands.
- ClientBinaryHandler [#]
  Handles client interaction - binary data.
- ClientWriteHandler [Optional Class]
  Handles client interaction - writing data (Only used in non-blocking mode).
- ClientAuthenticationHandler [Optional Class]
  Used to Authencatet a client.
- ClientData [Optional Class]
  Client data carrier (support class)
- ClientExtendedEventHandler [Optional Class]
  Handles extended client events.
[#] = Any one of these have to be set based on default DataMode for input. The default DataMode for input is String so if not changes you will have to set ClientCommandHandler.

Eg:
```
 package echoserver; import org.quickserver.net.*; import org.quickserver.net.server.*; import java.io.*; public class EchoServer { public static void main(String args[])	{ String cmdHandle = "echoserver.EchoCommandHandler"; QuickServer myServer = new QuickServer(); myServer.setClientCommandHandler(cmdHandle); myServer.setPort(4123); myServer.setName(Echo Server v1.0"); try { myServer.startServer(); } catch(AppException e) { System.err.println("Error in server : "+e); e.printStackTrace(); } } } 
```
