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.
