## com.sun.tools.doclets
Interface Taglet

public interface Taglet

The interface for a custom tag used by Doclets. A custom tag must implement this interface. To be loaded and used by doclets at run-time, the taglet must have a static method called `register` that accepts a `Map` as an argument with the following signature:

       public void register(Map map)

This method should add an instance of the custom taglet to the map with the name of the taglet as the key. If overriding a taglet, to avoid a name conflict, the overridden taglet must be deleted from the map before an instance of the new taglet is added to the map.

It is recommended that the taglet throw an exception when it fails to register itself. The exception that it throws is up to the user.

Here are two sample taglets:

- ToDoTaglet.java - Standalone taglet
- UnderlineTaglet.java - Inline taglet

For more information on how to create your own Taglets, please see the Taglet Overview.
