SimpleULogger (Apache Chainsaw 2.1.0-SNAPSHOT API)

java.lang.Object
- org.apache.log4j.spi.SimpleULogger

All Implemented Interfaces:: ULogger

public final class SimpleULogger
extends Object
implements ULogger

A simple implementation that logs messages of level INFO or higher on the console (System.out).

The output includes the relative time in milliseconds, thread name, level, logger name, and the message followed by the line separator for the host. In log4j terms it amounts to the "%r [%t] %level %logger - %m%n" pattern.

176 [main] INFO examples.Sort - Populating an array of 2 elements in reverse.
225 [main] INFO examples.SortAlgo - Entered the sort method.
304 [main] INFO SortAlgo.DUMP - Dump of interger array:
