extends Object

The LoggerFactory is a utility class producing Loggers for various logging APIs, most notably for log4j, logback and JDK 1.4 logging. Other implementations such as NOPLogger and SimpleLogger are also supported.

LoggerFactory is essentially a wrapper around an ILoggerFactory instance bound with LoggerFactory at compile time.
