All Implemented Interfaces:

Runnable

public class IRC
extends Thread

This is the base class which has to be used for an IRC connection. All other classes of this package are called from this one and don't have to be used in an other way. One exception is Ident, it can be used separately for establishing an ident server.

Constructor Detail

IRC

public IRC(String Server,
           short Port,
           String Channel,
           String Username,
           String Realname,
           MessagePipe TextOut,
           boolean retryOtherNicks,
           String DisconnectInfo)

The default constructor for an IRC object. This is the entry point for an IRC connection. Calling this function a Thread is started which connects to the server and tries to log in. That means the construction of an IRC object doesn't requires as much time as it needs for the whole connection and log-in-process. The information if this process could be performed successfully is submitted using the MessagePipe and an appropriate error or success code. The started thread finishes after the login process was completed. So during an IRC session only the protocol thread of IO is running.

Parameters:

Server - the name of the IRC server which has to be used

Port - the port number for the IRC connection

Channel - the name of the IRC channel, this name requires a leading "#" as known from the IRC channel names

Username - the user- or nickname to log into the IRC network with

Realname - the realname of the user which can be read using a "whois" request

TextOut - a MessagePipe which is used for the communication with the calling instance; this MessagePipe transfers all chat texts, error codes, information messages and so on

retryOtherNicks - if this parameter is set to true and the given Username already exists in IRC, it is tried to log in using other nicknames. These other names are constructed by appending the numbers from 1..9 to the given Username. If all these other nicknames aren't available too, the log in process fails

DisconnectInfo - a string which is displayed whenever the user leaves a channel. This string is used every time the connection has to be disconnected automatically. For an external triggered disconnect a separate reason can be specified.
