方法详细资料

• beforeInitialize

  public abstract void beforeInitialize()

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

• initialize

  public void initialize​(LoggingInitializationContext initializationContext,
                         String configLocation,
                         LogFile logFile)

  Fully initialize the logging system.

  参数:

  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

• cleanUp

  public void cleanUp()

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

• getShutdownHandler

  public Runnable getShutdownHandler()

  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.

  返回:

  the shutdown handler, or null

• getSupportedLogLevels

  public Set<LogLevel> getSupportedLogLevels()

  Returns a set of the LogLevels that are actually supported by the logging system.

  返回:

  the supported levels

• setLogLevel

  public void setLogLevel​(String loggerName,
                          LogLevel level)

  Sets the logging level for a given logger.

  参数:

  loggerName - the name of the logger to set (null can be used for the root logger).

  level - the log level (null can be used to remove any custom level for the logger and use the default configuration instead)

  public List<LoggerConfiguration> getLoggerConfigurations()

  Returns a collection of the current configuration for all a LoggingSystem's loggers.

  返回:

  the current configurations
