Java 9's Doclet API

Now that you have a good handle on the Doclet API as it existed prior to Java 9, let's look at what changes have been made and delivered with the Java 9 platform. The new Doclet API is in the jdk.javadoc.doclet package.

At a high level, the changes to the Doclet API are as follows:

Updates the com.sun.javadoc Doclet API to take advantage of several Java SE and JDK APIs
Updates the com.sun.tools.doclets.standard.Standard Doclet to use the new API
Supports the updated Taglet API that is used to create custom javadoc tags

In addition to the changes listed earlier, the new API uses the two APIs listed here:

Compiler tree API
Language model API

Let's explore each of these in the following sections.
