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