Method Detail

isLoggable

public static boolean isLoggable(Level level,
                                 Level threshold)

Verifies if the given level is above the required threshold for logging.

Parameters:

level - The Level to evaluate

threshold - The threshold Level

Returns:

true if the evaluated level is above the required threshold.

Note(s):

• If either argument is null then result is false.

• If the evaluated level is Level.OFF then result is false regardless of the threshold.

• If the threshold is Level.ALL and the evaluated level is not Level.OFF the result is true.

• Otherwise, the evaluated level Level.intValue() must be greater or equal to the threshold.

wrap

public static SimplifiedLog wrap(org.slf4j.Logger logger)

logMessage

public static void logMessage(org.slf4j.Logger logger,
                              Level level,
                              Object message,
                              Throwable t)

isLoggable

public static boolean isLoggable(org.slf4j.Logger logger,
                                 Level level)

Parameters:

logger - The Logger instance - ignored if null

level - The validate log Level - ignored if null

Returns:

true if the level is enabled for the logger. The mapping of the level to the logger is as follows:

• Level.OFF always returns false
• Level.SEVERE returns Logger.isErrorEnabled()
• Level.WARNING returns Logger.isWarnEnabled()
• Level.INFO and Level.ALL returns Logger.isInfoEnabled()
• Level.CONFIG and Level.FINE returns Logger.isDebugEnabled()
• All other levels return Logger.isTraceEnabled()
