Method Detail

receiveLogEvent

boolean receiveLogEvent(LogEvent le)

This method is called whenever a new log event has arrived for the subscriber to handle.

Returns:

when true, the log event was accepted by the listener's filter configuration, false otherwise

addedTo

void addedTo(LogBroadcaster le)

This method is called whenever this LogSubscriber is successfully attached to a LogBroadcaster. The LogSubscriber can use this event to keep a list of LogBroadcasters it is subscribed to, so it can easily remove itself from those when itself wants to get garbage-collected.

removedFrom

void removedFrom(LogBroadcaster le)

This method is called whenever this LogListener is removed from a LogBroadcaster. The LogBroadcaster can use this event to update its list of LogBroadcaster it is subscribed to.
