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.

  • Method Details

    • 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, Object message, 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
