java:

public class Message
extends java.lang.Object

This is the message class which captures information of a message Every logical message will result in at least two Message objects. One always goes to the message list of the sender user. The others, depending on whether the message was sent to a single user or a broadcast, will go to the message lists of the target user(s). For a one to one message (non broadcast messages), fromNickname and toNickname assume appropriate values. broadcastNickname is null for such cases. For broadcast messages, the sender Message object has a null for toNickname. Instead the broadcastNickname is populated. However, on the receivers' (people who belong to the broadcast list), the toNickname is their own nicknames. They have no idea it came through a broadcast. Hence, broadcastNickname is null for the Message objects that go to the receivers' message lists. fromNickname always assumes the sender's nickname. read is true for the sender's Message object. It's always false in the beginning, for the receivers' Message object until they read the message.
