0 # About SLF4J
1 The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time.
2 More information can be found on the [SLF4J website](http://www.slf4j.org).

6 # How to contribute pull requests
7 If you are interested in improving SLF4J, great! The SLF4J community looks forward to your contribution. Please follow this process:
8
9 1. Start a discussion on the [slf4j-dev mailing list](http://www.slf4j.org/mailing-lists.html) about your proposed change. Alternately file a [bug report](http://www.slf4j.org/bug-reporting.html).
10 2. Fork qos-ch/slf4j. Ideally, create a new branch from your fork for your contribution to make it easier to merge your changes back.
11 3. Make your changes on the branch you hopefuly created in Step 2. Be sure that your code passes existing unit tests. Please add unit tests for your work if appropriate. It usually is.
12 4. Push your changes to your fork/branch in github. Don't push it to your master! If you do it will make it harder to submit new changes later.
13 5. Submit a pull request to SLF4J from from your commit page on github.

19 * <p>A simple logging interface abstracting logging APIs. In order to be
20 * instantiated successfully by {@link LogFactory}, classes that implement
21 * this interface must have a constructor that takes a single String
22 * parameter representing the "name" of this Log.</p>
23 *
24 * <p> The six logging levels used by <code>Log</code> are (in order):
25 * <ol>
26 * <li>trace (the least serious)</li>
27 * <li>debug</li>
28 * <li>info</li>
29 * <li>warn</li>
30 * <li>error</li>
31 * <li>fatal (the most serious)</li>
32 * </ol>
33 * The mapping of these log levels to the concepts used by the underlying
34 * logging system is implementation dependent.
35 * The implementation should ensure, though, that this ordering behaves
36 * as expected.</p>
37 *
38 * <p>Performance is often a logging concern.
39 * By examining the appropriate property,
40 * a component can avoid expensive operations (producing information
41 * to be logged).</p>
42 *
43 * <p> For example,
44 * <code><pre>
45 * if (log.isDebugEnabled()) {
46 * ... do something expensive ...
47 * log.debug(theResult);
48 * }
49 * </pre></code>
50 * </p>
51 *
52 * <p>Configuration of the underlying logging system will generally be done
53 * external to the Logging APIs, through whatever mechanism is supported by
54 * that system.</p>
55 *
56 * <p style="color: #E40; font-weight: bold;">Please note that this interface is identical to that found in JCL 1.1.1.</p>

46 * logging detail level is used.</li>
47 * <li><code>org.apache.commons.logging.simplelog.showlogname</code> - Set to
48 * <code>true</code> if you want the Log instance name to be included in output
49 * messages. Defaults to <code>false</code>.</li>
50 * <li><code>org.apache.commons.logging.simplelog.showShortLogname</code> - Set

54 * <code>true</code> if you want the current date and time to be included in
55 * output messages. Default is <code>false</code>.</li>
56 * <li><code>org.apache.commons.logging.simplelog.dateTimeFormat</code> - The
57 * date and time format to be used in the output messages. The pattern
58 * describing the date and time format is the same that is used in
