public interface IRCBotModule
extends Comparable

This interface is used to create modules for the bot. Any module that wants to be notified with traffic from the IRC network needs to implement this interface or extend the AbstractIRCModule class.

Method Details

action

public String action(IRCMessage message)
action is invoked by the bot when someone types a message starting with a member of getCommands().
Parameters:
message - The original message sent to the channel. Provided if some command needs further information from it, like for instance the nick of the sender.
Returns:
A String containing a message to be sent to the IRC channel as a reply to the command invocation or null if no reply is needed.

activateEvent

public String activateEvent(IRCChannel channel)
Each module can schedule events to occur at some point in the future. When the future arrives and it is time for the event to be executed, this method is called.
Parameters:
channel - The channel in which the event is about to occur.
Returns:
A String containing the scheduled message to send to the channel, or null if no message needs to be sent.

getAuthor

public String getAuthor()

getCommands

public Collection getCommands(Modules.CommandType type)
getCommands is called to get the command line names of all commands provided by this module. An IRC message starting with a member of getCommands() will invoke this modules action method. All commands are lower case and begins with the command prefix (!). Note that a module's action method is ONLY called for commands returned by getCommands.
Parameters:
type - The needed privilege level needed to access this command.
Returns:
A Collection of String containing the commands provided by this module.
See Also:
Modules.CommandType

getDescription

public String getDescription(String topic,
                             Language lang)
getDescription is called to get the information printed by the !help command.
Parameters:
topic - Either the string returned by getModuleName().toLowerCase() or a member of getCommands(). The convention says that the call getDescription(getModuleName().toLowerCase()) should return a brief description about the module. This information should not overlap with information given by calls where the topic is a member of getCommands().
lang - What language to use for the reply.
Returns:
A String containing all the info needed to use this module, tailored to the given topic. If the topic is unexpected, the return value should be null.

getModuleName

public String getModuleName()
getModuleName is called to get the name of this module. The name is used when building the list of loaded modules. A module name may contain capital letters.
Returns:
A String containing the name of this module.

getProbability

public int getProbability()
getProbability is called to determine which module to choose to express a random thought whenever the bot feels like doing that.
Returns:
An integer value between 0 and 100 which represents the probability (percentage) that this module will be chosen to express a random thought. If your module has a broad variety of what is said and can be chosen several times in a row without getting boring, you should return a high probability (100 or just below). If your module does not have any random thoughts return a low probability (0).

loadState

public void loadState(SaveState state)
loadState is called when a module is loaded into the bot. It should read any settings or other external data needed for its operation from the provided state. Note that the data to be read has been saved by the saveState method in the same class. This method is only supposed to read values that has been saved by this class! If this module's saveState method does not save any data, this method should be empty. Data is read back from the state using the SaveState.get method.
Parameters:
state - The state to read from.

parseMessage

public String parseMessage(IRCMessage message)
parseMessage is called by the bot with every message that is sent to the IRC channel with the exception for messages beginning with a command prefix, and messages sent by the bot itself. If the implementing module does not care about the communication in the channel, this method should immediately return null without looking at the message.
Parameters:
message - The message sent to the IRC channel.
Returns:
A String containing a reply to the message, or null if nothing should be sent to the IRC channel.

randomThought

public String randomThought(IRCChannel channel,
                            Person sender)
An IRC bot might think that it has been too quiet in a channel for too long, or it may just feel like saying something at any given time. To get something to say a random module is chosen and its randomThought is invoked.
Parameters:
channel - The channel that is too quiet.
sender - The bot who asked for this thought.
Returns:
A String containing a random thought or null if this module has nothing nice to say.

saveState

public void saveState(SaveState state)
saveState is called when a module is unloaded from the bot or whenever the IRC command !save is issued. Use it to save any settings or other data needed for this modules operation. If this module does not keep any data that needs to be stored for later sessions, this method should be empty. Use the SaveState.add method to put new data into the state. Each data object that is to be stored in the state should be tagged with a unique identifier. The identifier will be padded with the name of the module so that identifiers in different modules will not clash.
Parameters:
state - The state to write to.

setModuleHandler

public void setModuleHandler(Modules handler)
setModuleHandler is called by the module handler when a module is loaded.
Parameters:
handler - The module handler that is loading the module.
