Interface Log

public interface Log

Interface that must be implemented the loggers returned by any LogFactory implementation. The logging methods defined by this interface represent the range of severity that may be associated with logging messages. How and where such messages are outputted is entirely up to the Log implementation. The logging severity levels are (in ascending order):

1. trace
2. debug
3. info
4. warn
5. error
6. fatal

In addition, each Log implementation must provide isXXXXEnabled() methods, where 'XXXX' are the various logging severity levels. These methods return booleans indicating whether logging messages at the associated logging level will be outputted.
