| aoqi@0 | 32 | * The interface for a custom tag used by Doclets. A custom |
| aoqi@0 | 33 | * tag must implement this interface. To be loaded and used by |
| aoqi@0 | 34 | * doclets at run-time, the taglet must have a static method called |
| aoqi@0 | 35 | * <code>register</code> that accepts a {@link java.util.Map} as an |
| aoqi@0 | 36 | * argument with the following signature: |
| aoqi@0 | 37 | * <pre> |
| aoqi@0 | 38 | * public void register(Map map) |
| aoqi@0 | 39 | * </pre> |
| aoqi@0 | 40 | * This method should add an instance of the custom taglet to the map |
| aoqi@0 | 41 | * with the name of the taglet as the key. If overriding a taglet, |
| aoqi@0 | 42 | * to avoid a name conflict, the overridden taglet must be deleted from |
| aoqi@0 | 43 | * the map before an instance of the new taglet is added to the map. |
| aoqi@0 | 44 | * <p> |
| aoqi@0 | 45 | * It is recommended that the taglet throw an exception when it fails |
| aoqi@0 | 46 | * to register itself. The exception that it throws is up to the user. |
| aoqi@0 | 47 | * <p> |
| aoqi@0 | 48 | * Here are two sample taglets: <br> |
| aoqi@0 | 49 | * <ul> |
| aoqi@0 | 50 | * <li><a href="{@docRoot}/ToDoTaglet.java">ToDoTaglet.java</a> |
| aoqi@0 | 51 | * - Standalone taglet</li> |
| aoqi@0 | 52 | * <li><a href="{@docRoot}/UnderlineTaglet.java">UnderlineTaglet.java</a> |
| aoqi@0 | 53 | * - Inline taglet</li> |
| aoqi@0 | 54 | * </ul> |
| aoqi@0 | 55 | * <p> |
| aoqi@0 | 56 | * For more information on how to create your own Taglets, please see the |
| aoqi@0 | 57 | * <a href="{@docRoot}/overview.html">Taglet Overview</a>. |
