Class JULLogger

java.lang.Object
  com.aragost.javahg.log.JULLogger

All Implemented Interfaces:

Logger

public class JULLogger
extends Object
implements Logger

This simulates the Logger class from slf4j.

Only the methods that is actually used by JavaHg is implemented, but others will be added as needed.

Implementation note: In general for log level abc there is an void abc(String msg) and void abc(String msg, Object[] args). The first simply writes the message to the backend with no formatting, the second will do a formatting similar to slf4j. The first is strictly not needed, but the consequence would be that for even simple log messages a temp array would be created for the varargs.

Method Detail

debug

public void debug(String msg)

Description copied from interface: Logger

Logs a debugging message - detailed debugging information that can be used for identifying problems without a debugger, e.g. entry/exit points, user errors, recoverable errors, algorithm steps. The application performance is significantly reduced when this logging level is enabled. Not for production use.

Specified by:

debug in interface Logger

Parameters:

msg - The message to log.
