Callback routine. This is called when we want to log a message. Since this routine is pure virtual, it must be overwritten by the subclass. |
Users who are interested in getting the logging messages directly, can subclass this interface and override the log() method. They must then register their subclass with the Log_Msg class and make sure that they turn on the ACE_Log_Msg::MSG_CALLBACK flag.
Your <log> routine is called with an instance of ACE_Log_Record. From this class, you can get the log message, the verbose log message, message type, message priority, and so on.
Remember that there is one Log_Msg object per thread. Therefore, you may need to register your callback object with many objects (and have the correct synchronization in the <log> method) or have a separate callback object per Log_Msg object. Moreover, are not inherited when a new thread is spawned, so you'll need to reset these in each new thread.
