Document! X for Java Documentation

Automated Java Documentation Tool + WYSIWYG Authoring Environment

Document! X delivers the best of both worlds by seamlessly combining automatic documentation of Java Projects with a full WYSIWYG authoring environment. The generated content is an accurate and comprehensive documentation set for your Java Project covering packages, classes, interfaces, enumerations, methods, and fields.

Document! X will use any existing Javadoc source code comments and you can extend the source descriptions using the rich authoring environment provided by the Document! X Content File Editor.

Object Model Diagrams

Document! X automatically generates object relationship diagrams for your classes. Specific relationships can be ignored where necessary (e.g. a relationship back to a parent object). Collection objects are automatically recognized and appropriately represented.

Single Source Build and Publish

Your documentation projects can be built to Browser Help or CHM (Html Help 1.x). The specific requirements for the different output formats are handled for your automatically and you can build all outputs from a single project. Automatic publishing makes it quick and simple to deploy the generated output to your web site, ftp server or network location.
