* It provides an event-driven architecture to handle common IRC * events, flood protection, DCC support, ident support, and more. * The comprehensive logfile format is suitable for use with pisg to generate * channel statistics. *

* Methods of the PircBot class can be called to send events to the IRC server * that it connects to. For example, calling the sendMessage method will * send a message to a channel or user on the IRC server. Multiple servers * can be supported using multiple instances of PircBot. *

* To perform an action when the PircBot receives a normal message from the IRC * server, you would override the onMessage method defined in the PircBot * class. All onXYZ methods in the PircBot class are automatically called * when the event XYZ happens, so you would override these if you wish * to do something when it does happen. *

* Some event methods, such as onPing, should only really perform a specific * function (i.e. respond to a PING from the server). For your convenience, such * methods are already correctly implemented in the PircBot and should not * normally need to be overridden. Please read the full documentation for each * method to see which ones are already implemented by the PircBot class. *

* Please visit the PircBot homepage at * http://www.jibble.org/pircbot.php * for full revision history, a beginners guide to creating your first PircBot * and a list of some existing Java IRC bots and clients that use the PircBot * framework. * * @author Paul James Mutton, * http://www.jibble.org/ * @version 1.5.0 (Build time: Mon Dec 14 20:07:17 2009) */ public abstract class PircBot implements ReplyConstants { /** * The definitive version number of this release of PircBot. * (Note: Change this before automatically building releases) */ public static final String VERSION = "1.5.0"; private static final int OP_ADD = 1; private static final int OP_REMOVE = 2; private static final int VOICE_ADD = 3; private static final int VOICE_REMOVE = 4; /** * Constructs a PircBot with the default settings.
