getCompositeLog

public static Logger getCompositeLog(Logger primaryLogger,
 Logger secondaryLogger,
 Logger... tertiaryLoggers)

Create a composite logger that delegates to a primary or falls back on a secondary logger if logging for the primary logger is not enabled.

This may be used for fallback logging from lower-level packages that logically should log together with some higher-level package but the two don't happen to share a suitable parent package (e.g. logging for the web and lower-level http and codec packages). For such cases the primary (class-based) logger can be wrapped with a shared fallback logger.

参数:

primaryLogger - primary logger to try first

secondaryLogger - secondary logger

tertiaryLoggers - optional vararg of further fallback loggers

返回:

the resulting composite logger for the related categories

getHiddenLog

public static Logger getHiddenLog(Class<?> clazz)

Create a "hidden" logger with a category name prefixed with "_", thus precluding it from being enabled together with other log categories from the same package. This is useful for specialized output that is either too verbose or otherwise optional or unnecessary to see all the time.

参数:

clazz - the class for which to create a logger

返回:

a Logger with the category "_" + fully-qualified class name

getHiddenLog

public static Logger getHiddenLog(String category)

Create a "hidden" logger with a category name prefixed with "_", thus precluding it from being enabled together with other log categories from the same package. This is useful for specialized output that is either too verbose or otherwise optional or unnecessary to see all the time.

参数:

category - the log category to use

返回:

a Logger with the category "_" + category
