Package net.spy.memcached.compat.log

Class SLF4JLogger

java.lang.Object

net.spy.memcached.compat.log.AbstractLogger

net.spy.memcached.compat.log.SLF4JLogger

All Implemented Interfaces:

Logger

public class SLF4JLogger
extends AbstractLogger

Logging Implementation using the SLF4J logging facade.

Note that by design, the SLF4J facade does not ship with an actual implementation so that it can be chosen during runtime. If you fail to provide a logging implementation during runtime, no log messages will be logged. See the SLF4J Manual for more information on how to do this.

Since SLF4J does not support a FATAL log level, errors logged at that level get promoted down to ERROR, since this is the highest level available.

Constructor Detail

SLF4JLogger

public SLF4JLogger(java.lang.String name)

Get an instance of the SLF4JLogger.

Method Detail

isTraceEnabled

public boolean isTraceEnabled()

Description copied from interface: Logger

Checks whether TRACE logging is enabled. This may return true, even when the logger is configured to not put the resulting output anywhere. You can use this method to avoid potential expensive (debugging) code when there is no need for it since it will be dropped anyway:

if (log.isTraceEnabled()) {
  ... expensive code here ...
  log.trace(result);
}
 

Returns:

true if trace messages would be displayed.

isDebugEnabled

public boolean isDebugEnabled()

Description copied from class: AbstractLogger

True if debug is enabled for this logger. Default implementation always returns false

Specified by:

isDebugEnabled in interface Logger

Specified by:

isDebugEnabled in class AbstractLogger

Returns:

true if debug messages would be displayed

isInfoEnabled

public boolean isInfoEnabled()

Description copied from class: AbstractLogger

True if debug is enabled for this logger. Default implementation always returns false

Specified by:

isInfoEnabled in interface Logger

Specified by:

isInfoEnabled in class AbstractLogger

Returns:

true if info messages would be displayed

log

public void log(Level level,
                java.lang.Object message,
                java.lang.Throwable e)

Wrapper around SLF4J logger facade.

Specified by:

log in interface Logger

Specified by:

log in class AbstractLogger

Parameters:

level - net.spy.compat.log.Level level.

message - object message

e - optional throwable
