Method Detail
beforeInitialize
public void beforeInitialize()
Description copied from class:LoggingSystemReset the logging system to be limit output. This method may be called beforeLoggingSystem.initialize(LoggingInitializationContext, String, LogFile)to reduce logging noise until the system has been fully initialized.- Overrides:
beforeInitializein classAbstractLoggingSystem
cleanUp
public void cleanUp()
Description copied from class:LoggingSystemClean up the logging system. The default implementation does nothing. Subclasses should override this method to perform any logging system-specific cleanup.- Overrides:

Description copied from class:AbstractLoggingSystemLoad a specific configuration.- Specified by:
loadConfigurationin classAbstractLoggingSystem- Parameters:
initializationContext- the logging initialization contextlocation- the location of the configuration to load (nevernull)logFile- the file to load ornullif no log file is to be written
