requiresLayout
public boolean requiresLayout()Description copied from interface:Appender
Configurators call this method to determine if the appender requires a layout. If this method returnstrue
, meaning that layout is required, then the configurator will configure an layout using the configuration information at its disposal. If this method returnsfalse
, 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
.- Returns:
- true if a Layout is required.
