| <p>"-javaagent" routines for SLF4J.</p> |
| <p>The "-javaagent" flag provided in Java 5+ allows for writing |
| agents in Java, which previously was possible in native code only. The |
| full details are available at <a |
| href="http://java.sun.com/javase/6/docs/api/java/lang/instrument/package-summary.html">http://java.sun.com/javase/6/docs/api/java/lang/instrument/package-summary.html</a>. |
| |
| |
| Please notice that code made available to the java agent is also |
| available to the actual program executed.</p> |
| <p>The slf4j-ext-X.Y.Z.jar file provides such a java agent, which is |
| implemented in AgentPremain.java. It is used by adding a -javaagent flag to the Java command line: |
| |
| E.g. |
| <pre><code>java HelloWorld</code></pre> |
| is changed to |
| <pre><code>java -javaagent:/path/to/slf4j-ext-X.Y.Z.jar=<em>OPTIONS</em> HelloWorld</code></pre> |
| |
| <p>What is actually done, depends on the <em>OPTIONS</em> passed to the agent. These are listed in AgentOptions.java. |
