org.slf4j.impl.SimpleLogger
| SimpleLogger | | public class SimpleLogger extends MarkerIgnoringBase (Code) | | A simple (and direct) implementation that logs messages of level
INFO or higher on the console (System.err).
The output includes the relative time in milliseconds, thread
name, the 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.
Sample output follows.
176 [main] INFO examples.Sort - Populating an array of 2 elements in reverse order.
225 [main] INFO examples.SortAlgo - Entered the sort method.
304 [main] INFO examples.SortAlgo - Dump of integer array:
317 [main] INFO examples.SortAlgo - Element [0] = 0
331 [main] INFO examples.SortAlgo - Element [1] = 1
343 [main] INFO examples.Sort - The next log statement should be an error message.
346 [main] ERROR examples.SortAlgo - Tried to dump an uninitialized array.
