Haxe to Java Extern Creator

A java program which parses folders of Java .class files, and exports a folder containing a list of [Haxe] (http://haxe.org/) external definitions.

Features

• Uses javadoc, so you get meaningful variable names, and full code commenting
• Constant values are inlined
• Inner classes are renamed with an underscore, and placed into the same file as the outer class (e.g. Outer.Inner becomes Outer_Inner)
• Multithreading means fast extern creation

Useage

This program must be built to include tools.jar, which can be found at jdk-loc/lib/tools.jar

The program can be run using java -jar (jar-file) -source (source-dir) -output (output-dir) -packages (package-list)

This will create matching haxe externs in (output-dir) for each java class in the specified packages, looking in (source-dir)

Note: the output directory will be structured based on the class hierarchy of the java files input. Also, all existing files that match classes in the input directory will be overwritten

Example

The following is example output for [android.widget.Toast] (http://developer.android.com/reference/android/widget/Toast.html).

package android.widget;

@:native("android.widget.Toast")
/**
 * A toast is a view containing a quick little message for the user.  The toast class
 * helps you create and show those.
 * {@more}
 *
 * <p>
 * When the view is shown to the user, appears as a floating view over the
 * application.  It will never receive focus.  The user will probably be in the
 * middle of typing something else.  The idea is to be as unobtrusive as
 * possible, while still showing the user the information you want them to see.
 * Two examples are the volume control, and the brief message saying that your
 * settings have been saved.
 * <p>
 * The easiest way to use this class is to call one of the static methods that constructs
 * everything you need and returns a new Toast object.
 *
 * <div class="special reference">
 * <h3>Developer Guides</h3>

 * guide.</p>
