Method Detail

log

public void log(InternalLogger.Level level,

                java.lang.Throwable ex)

Description copied from interface: InternalLogger

Logs the message to an appropriate OSGi logger. If not such logger can be found then it will log to stderr for ERROR & AUDIT messages and stdout for other messages

Specified by:

log in interface InternalLogger

Parameters:

level - only log when this level is implied by the current log level

message - the message to log

ex - a Throwable or null

log

public void log(InternalLogger.Level level,
                java.lang.String message,
                java.lang.Throwable ex,
                java.lang.Object... args)

Description copied from interface: InternalLogger

Formats the message using the MessageFormat class, i.e. with {} place holders for the args. It then calls InternalLogger.log(Level, String, Throwable).

Specified by:

log in interface InternalLogger

Parameters:

level - only log when this level is implied by the current log level

message - the message to log

ex - a Throwable or null

args - the arguments to the MessageFormat formatting

isLogEnabled

public boolean isLogEnabled(InternalLogger.Level level)

Description copied from interface: InternalLogger

Answer true if the current logging level is enabled for the given level. For stdout/stderr fallback the logging level is defined by the LogConfiguration.getLogLevel(). If there is an OSGi logger available then the logger name will define the log level via LoggerAdmin.

true if the given log level is enabled

setComponentId
