Class IChatMessage

java.lang.Object
  com.web_visage.ichat.IChatMessage

All Implemented Interfaces:

IChatMessageConstants

Direct Known Subclasses:

IChatAlertMessage, IChatBoardMessage, IChatConnectMessage, IChatCreateLineMessage, IChatCreateMessage, IChatDisconnectMessage, IChatMeMessage, IChatReceivedMessage, IChatRefreshBoardMessage, IChatRefreshMessage, IChatRenameMessage, IChatStatusMessage, IChatStatusReqMessage, IChatTextMessage

public abstract class IChatMessage
extends java.lang.Object
implements IChatMessageConstants

Represents abstract iChat message structure.

iChat message pattern is following:
[0x13] ["iChat"] [incremental id string] [0x13 0x13] [sender] [0x13 0x13] [command name] [0x13 0x13] [command parameters]
Command parameter pattern is following:
[parameter string] [0x13 0x13] [parameter string] [0x13]

This implementation is not completely immutable since it changes it's inner state, but is is free from the external changes and is compeletely thread-safe.
