  - getStandardConfigLocations
```
protected String[] getStandardConfigLocations()
```
    Description copied from class: AbstractLoggingSystem
    
    Return the standard config locations for this system.
    
    Specified by:
    
    getStandardConfigLocations in class AbstractLoggingSystem
    
    Returns:
    
    the standard config locations

    AbstractLoggingSystem.getSelfInitializationConfig()
  - 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 Slf4JLoggingSystem
  - initialize
```
public void initialize(LoggingInitializationContext initializationContext,
                       String configLocation,
                       LogFile logFile)
```
    Description copied from class: LoggingSystem
    
    Fully initialize the logging system.
    
    Overrides:
    
    initialize in class AbstractLoggingSystem
    
    Parameters:
    
    initializationContext - the logging initialization context
    
    configLocation - a log configuration location or null if default initialization is required
    
    logFile - the log output file that should be written or null for console only output
  - loadDefaults
```
protected void loadDefaults(LoggingInitializationContext initializationContext,
                            LogFile logFile)
```
    Description copied from class: AbstractLoggingSystem
    
    Load sensible defaults for the logging system.
    
    Specified by:
    
    loadDefaults in class AbstractLoggingSystem
    
    Parameters:
    
    initializationContext - the logging initialization context
    
    logFile - the file to load or null if no log file is to be written
  - loadConfiguration
```
protected void loadConfiguration(LoggingInitializationContext initializationContext,
                                 String location,
                                 LogFile logFile)
```
    Description copied from class: AbstractLoggingSystem
    
    Load a specific configuration.
    
    Overrides:
    
    loadConfiguration in class Slf4JLoggingSystem
    
    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
  - 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 Slf4JLoggingSystem
  - reinitialize
```
protected void reinitialize(LoggingInitializationContext initializationContext)
```
    Description copied from class: AbstractLoggingSystem
    
    Reinitialize the logging system if required. Called when AbstractLoggingSystem.getSelfInitializationConfig() is used and the log file hasn't changed. May be used to reload configuration (for example to pick up additional System properties).
    
    Overrides:
    
    reinitialize in class AbstractLoggingSystem
    
    Parameters:
    
    initializationContext - the logging initialization context
  - getLoggerConfigurations
```
public List<LoggerConfiguration> getLoggerConfigurations()
```
    Description copied from class: LoggingSystem
    
    Returns a collection of the current configuration for all a LoggingSystem's loggers.
    
    Overrides:
    
    getLoggerConfigurations in class LoggingSystem
    
    Returns:
    
    the current configurations
  - getLoggerConfiguration
```
public LoggerConfiguration getLoggerConfiguration(String loggerName)
```
    Description copied from class: LoggingSystem
    
    Returns the current configuration for a LoggingSystem's logger.
    
    Overrides:
    
    getLoggerConfiguration in class LoggingSystem
    
    Parameters:
    
    loggerName - the name of the logger
    
    Returns:
    
    the current configuration
  - getSupportedLogLevels
```
public Set<LogLevel> getSupportedLogLevels()
```
    Description copied from class: LoggingSystem
    
    Returns a set of the LogLevels that are actually supported by the logging system.
    
    Overrides:
    
    getSupportedLogLevels in class LoggingSystem
    
    Returns:
    
    the supported levels
  - setLogLevel
```
public void setLogLevel(String loggerName,
                        LogLevel level)
```
    Description copied from class: LoggingSystem
    
    Sets the logging level for a given logger.
    
    Overrides:
    
    setLogLevel in class LoggingSystem
    
    Parameters:
    
    loggerName - the name of the logger to set (null can be used for the root logger).
    
    level - the log level
  - getShutdownHandler
```
public Runnable getShutdownHandler()
```
    Description copied from class: LoggingSystem
    
    Returns a Runnable that can handle shutdown of this logging system when the JVM exits. The default implementation returns null, indicating that no shutdown is required.
