public void append(LogEvent event)
Description copied from interface:Appender
Logs a LogEvent using whatever logic this Appender wishes to use. It is typically recommended to use a bridge pattern not only for the benefits from decoupling an Appender from its implementation, but it is also handy for sharing resources which may require some form of locking.- Parameters:
event
- The LogEvent.
