Interface Log

All Known Implementing Classes:

BandyLogger, Log4jLogger, MicrologLogger

public interface Log

This interface provides a common abstraction of a 'Logger' object. Classes implementing this interface typically are thin wrappers around existing logging frameworks (as log4j or microlog). By programming to this interface, a client class is decoupled from a specific logging framework and, since most frameworks are platform dependent (J2SE vs. J2ME), as well from a specific platform.
Note: an underlying logging framework is best configured in its respective configuration file (e.g. log4j.properties, microlog.properties).
This interface provides the following log levels (from low to high severity):
trace, debug, info, warn, error, fatal.
For a usage example see LogFactory.
