Channel Class

Note: Currently the information is pre-release, and could be changed at any time before the release. Please refer to the code for the most accurate use of this object.

The channel class has all the functionality to manage a channel and its users. It is recommended that you instantiate a new channel through the servers Join method, and retrieve it by using the GetChannel method. It is very important that you remember to suffix the channel name with the # symbol.

     Channel chan = server.GetChannel("#YourChannel");

Once you have joined a channel, you can send a message by using the Send method. When using this method, the PRIVMSG and channel name are already assumed and should not be given to the Send method.

     server.GetChannel("#YourChannel")->Send("This is your message");

When you join a channel, Modesto will automatically check to see who is in the channel, and then auto-populate the user list. You can check to see how many users there are by calling NumUsers, or find out is in the room by using the HasUser method. You can also retrieve the user by calling GetUser. If you'd like to know more about the User class, then please visit the User Class page.

     if (server.GetChannel("#YourChannel")->HasUser("NickName"))
          User usr = server.GetChannel("#YourChannel")->GetUser("NickName");

If you need to check if the user exists so that you can call a method on the user class, then we suggest you skip the HasUser method, and go directly to calling GetUser which will return a NULL value if the user does not exist.

     if (User usr = server.GetChannel("#YourChannel")->GetUser("NickName"))


Below is an example of how to retrieve and use the Channel class. This will only work if you have already connected to the server by using the Server Class.


     if (Channel chan = serv.GetChannel("#MyChannel"))
          chan->Send("Hello channel, I am Modesto");

          if (chan->HasUser("MasterChief"))
               chan->Send("I see you MasterChief, let's take this to PM");
          if (User usr = chan->GetUser("MasterChief"))
               usr->Send("It's good to see you again MasterChief!");
