-<h1>Java Agent</h1>
-
-<p>
- JaCoCo uses class file instrumentation to record execution coverage data.
- Class files are instrumented on-the-fly using a so called Java agent. This
- mechanism allows in-memory pre-processing of all class files during class
- loading independent of the application framework.
-</p>
-
-<p class="hint">
- If you use the <a href="ant.html">JaCoCo Ant tasks</a> or <a href="maven.html">JaCoCo Maven plug-in</a>
- you don't have to care about the agent and its options directly. This is
- transparently handled by the them.
-</p>
-
-<p>
- The JaCoCo agent collects execution information and dumps it on request or
- when the JVM exits. There are three different modes for execution data ouput:
-</p>
-
-<ul>
- <li>File System: At JVM termination execution data is written to a local file.</li>
- <li>TCP Socket Server: External tools can connect to the JVM and retrieve execution data over the socket connection. Optional execution data reset and execution data dump on VM exit is possible.</li>
- <li>TCP Socket Client: At startup the JaCoCo agent connects to a given TCP endpoint. Execution data is written to the socket connection on request. Optional execution data reset and execution data dump on VM exit is possible.</li>
- <li>JMX: External tools can connect to the JVM and retrieve execution data over the JMX.</li>
-</ul>
-
-<p>
- The agent <code>jacocoagent.jar</code> is part of the JaCoCo distribution and
- includes all required dependencies. A Java agent can be activated with the
- following JVM option:
-</p>
-
-<pre>
- -javaagent:<i>[yourpath/]</i>jacocoagent.jar=<i>[option1]</i>=<i>[value1]</i>,<i>[option2]</i>=<i>[value2]</i>
-</pre>
-
-<p>
- The JaCoCo agent accepts the following options:

- The ports and connections opened in <code>tcpserver</code> and

- targets. Otherwise internal information of the application might be revealed
- or DOS attacks are possible.
