public class IPCServer

extends java.lang.Thread

A network server. Once started, the server listens for incoming connections, accepts them and then handles them. The handle method must be overriden in subclasses.

Field Summary

protected java.net.ServerSocket	socket Socket for incoming connections

Constructor Summary

IPCServer()
default class constructor

IPCServer(int p)
Class constructor

Method Summary

protected IPCConnection	accept() Waits for a connection (blocks until a client tries to connect)
protected boolean	bind() Binds the server to the specified port
void	handle(IPCConnection connection) This is a deferred method for handling an incoming connection.
void	run() Overriden method.
void	start() Starts a thread (overriden method).

Field Detail

port

public int port

Port number for listening (default 80)

socket

protected java.net.ServerSocket socket

Socket for incoming connections

Constructor Detail

IPCServer

public IPCServer()

default class constructor

IPCServer

public IPCServer(int p)

Class constructor

Parameters:

p - the port number for listening

Method Detail

accept

protected IPCConnection accept()

Waits for a connection (blocks until a client tries to connect)

Returns:

The connection or null.

bind

protected boolean bind()

Binds the server to the specified port

Returns:

true if operation was ok or false if an error occurs

start

public void start()

Starts a thread (overriden method). Bind the server to the specified port.

Overrides:

start in class java.lang.Thread

run

public void run()

Overriden method. There is an infinite loop with two actions: accept and handle. That is: wait for a connection and then process it.

Overrides:

run in class java.lang.Thread

handle

public void handle(IPCConnection connection)

This is a deferred method for handling an incoming connection. A subclass must override this method. The handle here only closes the incoming connection.

Parameters:

connection - the incoming connection from the client
