setAllLevels

public static void setAllLevels(String parentLogger,
                org.apache.logging.log4j.Level level)

Sets the levels of parentLogger and all 'child' loggers to the given level.

Parameters:

parentLogger - the parent logger

level - the new level

setLevel

public static void setLevel(Map<String,org.apache.logging.log4j.Level> levelMap)

Sets logger levels.

Parameters:

levelMap - a levelMap where keys are level names and values are new Levels.

setLevel

public static void setLevel(String loggerName,
            org.apache.logging.log4j.Level level)

Sets a logger's level.

Parameters:

loggerName - the logger name

level - the new level

setRootLevel

public static void setRootLevel(org.apache.logging.log4j.Level level)

Sets the root logger's level.

Parameters:

level - the new level

shutdown

public static void shutdown(LoggerContext ctx)

Shuts down the given logger context. This request does not wait for Log4j tasks to complete.

Log4j starts threads to perform certain actions like file rollovers; calling this method will not wait until the rollover thread is done. When this method returns, these tasks' status are undefined, the tasks may be done or not.

Parameters:

ctx - the logger context to shut down, may be null.

shutdown

public static boolean shutdown(LoggerContext ctx,
               long timeout,
               TimeUnit timeUnit)

Shuts down the given logger context.

Log4j can start threads to perform certain actions like file rollovers; calling this method with a positive timeout will block until the rollover thread is done.

Parameters:

ctx - the logger context to shut down, may be null.

timeout - the maximum time to wait

timeUnit - the time unit of the timeout argument

Returns:

true if the logger context terminated and false if the timeout elapsed before termination.

Since:

2.7
