DocletEnvironment

DocletEnvironment is an interface in the Java programming language documentation tool, Javadoc. It represents the Javadoc tool's environment during the execution of a custom doclet. A doclet is a program that specifies the output format for Javadoc, allowing developers to customize how their API documentation is generated. The DocletEnvironment interface provides access to various aspects of the Javadoc processing, including the set of packages, classes, and members being documented.

Implementations of DocletEnvironment are created by the Javadoc tool itself when a doclet is invoked. Developers writing custom doclets use the methods provided by this interface to retrieve information about the code they are documenting. For instance, they can query for specific classes, inspect their methods and fields, and access Javadoc comments associated with them. This allows doclets to generate documentation in a wide range of formats, from standard HTML to custom formats like XML, JSON, or even executables. The interface also provides access to configuration options and utility methods for interacting with the Javadoc tool. Essentially, DocletEnvironment acts as a bridge between the Javadoc tool and the custom doclet, enabling sophisticated documentation customization.
