Message Sender

It sends messages to a specific entity according to a mode

Definition

public interface MessageSender<E> {
    
  default void send(E receiver, String mode, StringList messages) {
    send(receiver, mode, messages.join("\n"));
  }
  
  void send(E receiver, String mode, String message);

}

The method provides the receiver (the entity that must receive the given message), the mode (how to send the message, this will be explained later), and the sent message.

Implementation

public class UserMessageSender implements MessageSender<User> {
  @Override
  public void send(User receiver, String mode, String message) {
    // you can also add "outputs" (ex. window message, console message, etc)
    switch (mode) {
      case "info":
        receiver.send(message);
        break;
      case "warn":
        receiver.warn(message);
        break;
      case "severe":
        receiver.severe(message);
        break;
    }
  }
}

Configuring

Set the Messenger for a specific type while constructing MessageHandler

MessageHandler handler = MessageHandler.of(
    source,
    config -> {
      // set the message sender
      config.specify(User.class)
            .setMessageSender(new UserMessageSender())
            // it's a fluent API, you can also set the linguist here
            .setLinguist(new UserLinguist());
    }
);
