IntelliJ IDEA Plugin that helps generating Value classes

ValueClassGenerator

IntelliJ IDEA Plugin that helps generating Value classes without the need to add any libs to your build (like google autovalue or project lombok).

Features

done

• primitives/primitive wrapper will be subclassed
• equals/hashcode/toString

soon™

• see enhancement issues

Usage

1. Create your data class and define your properties
2. right-click into the editor and click onto the Generate value class button
