  - beforeInitialize
```
public void beforeInitialize()
```
    从类复制的说明: 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.
    覆盖:
    beforeInitialize 在类中 AbstractLoggingSystem
  - cleanUp
```
public void cleanUp()
```
    从类复制的说明: LoggingSystem
    Clean up the logging system. The default implementation does nothing. Subclasses should override this method to perform any logging system-specific cleanup.
    覆盖:
    cleanUp 在类中 LoggingSystem
  - loadConfiguration
```
protected void loadConfiguration(LoggingInitializationContext initializationContext,
                                 String location,
                                 LogFile logFile)
```
    从类复制的说明: AbstractLoggingSystem
    Load a specific configuration.
    指定者:
    loadConfiguration 在类中 AbstractLoggingSystem
    参数:
    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
  - isBridgeJulIntoSlf4j
```
protected final boolean isBridgeJulIntoSlf4j()
```
    Return whether bridging JUL into SLF4J or not.
    返回:
    whether bridging JUL into SLF4J or not
