Method Detail

beforeInitialize

public void beforeInitialize()

Description copied from class: LoggingSystem

Reset the logging system to be limit output. This method may be called before LoggingSystem.initialize(LoggingInitializationContext, String, LogFile) to reduce logging noise until the system has been fully initialized.

Overrides:

beforeInitialize in class AbstractLoggingSystem

cleanUp

public void cleanUp()

Description copied from class: LoggingSystem

Clean up the logging system. The default implementation does nothing. Subclasses should override this method to perform any logging system-specific cleanup.

Overrides:

cleanUp in class LoggingSystem

loadConfiguration

protected void loadConfiguration(LoggingInitializationContext initializationContext,
                                 String location,
                                 LogFile logFile)

Description copied from class: AbstractLoggingSystem

Load a specific configuration.

Specified by:

loadConfiguration in class AbstractLoggingSystem

Parameters:

initializationContext - the logging initialization context

location - the location of the configuration to load (never null)

logFile - the file to load or null if no log file is to be written
