31 * The interface for a custom tag used by Doclets. A custom
32 * tag must implement this interface. To be loaded and used by
33 * doclets at run-time, the taglet must have a static method called
34 * <code>register</code> that accepts a {@link java.util.Map} as an
35 * argument with the following signature:
36 * <pre>
37 * public void register(Map map)
38 * </pre>
39 * This method should add an instance of the custom taglet to the map
40 * with the name of the taglet as the key. If overriding a taglet,
41 * to avoid a name conflict, the overridden taglet must be deleted from
42 * the map before an instance of the new taglet is added to the map.
43 * <p>
44 * It is recommended that the taglet throw an exception when it fails
45 * to register itself. The exception that it throws is up to the user.
46 * <p>
47 * Here are two sample taglets: <br>
48 * <ul>
49 * <li><a href="{@docRoot}/../../../../technotes/guides/javadoc/taglet/ToDoTaglet.java">ToDoTaglet.java</a>
50 * - Standalone taglet</li>
51 * <li><a href="{@docRoot}/../../../../technotes/guides/javadoc/taglet/UnderlineTaglet.java">UnderlineTaglet.java</a>
52 * - Inline taglet</li>
53 * </ul>
54 * <p>
55 * For more information on how to create your own Taglets, please see the
56 * <a href="{@docRoot}/../../../../technotes/guides/javadoc/taglet/overview.html">Taglet Overview</a>.
