Method Detail

onLogMessage

public void onLogMessage(LogMessage msg)

Description copied from interface: LogMessageListener

Called when the message is received. The implementation should be thread-safe: the framework makes no guarantees on what thread this method will be called on, and it can be called concurrently for several messages. The implementation should also return immediately : any blocking operations should be scheduled on a separate thread.

Specified by:

onLogMessage in interface LogMessageListener

Parameters:

msg - Log bus message to be processed.
