It is a programming error to append to a closed appender.
Log in Appender
specific way. When appropriate,
Loggers will call the doAppend
method of appender
implementations in order to log.
Returns the head Filter. The Filters are organized in a linked list and so all Filters on this Appender are available through the result.
Get the name of this appender.
Configurators call this method to determine if the appender
requires a layout. If this method returns true
,
meaning that layout is required, then the configurator will
configure an layout using the configuration information at its
disposal. If this method returns false
, meaning that
a layout is not required, then layout configuration will be
skipped even if there is available layout configuration
information at the disposal of the configurator..
In the rather exceptional case, where the appender
implementation admits a layout but can also work without it, then
the appender should return true
.
Set the ErrorHandler
for this appender.
Set the name of this appender. The name is used by other components to identify this appender.
