摘要

本文提出了一种没有类的OO风格，我们称之为基于接口的面向对象编程(IB)。IB是一个密切相关的概念，如特征的自然延伸。抽象状态操作提供了一种处理状态的新方法，它提供了基于类的语言所不具备的灵活性。在IB状态下可以在子类型中进行类型细化。纯IB风格和类型细化的结合使用多重继承和状态实现了强大的习惯用法。为了向程序员介绍IB，我们创建了无类Java:将IB直接嵌入到Java中。无类Java使用注释处理来生成代码，并依赖于Java 8的新特性来实现接口。无类Java中使用的代码生成技术有一些有趣的特性，包括保证生成的代码是类型安全的，并与ide很好地集成。通过示例和案例研究展示了IB和无类Java的有用性。

Classless Java

This paper presents an OO style without classes, which we call interface-based object-oriented programming (IB). IB is a natural extension of closely related ideas such as traits. Abstract state operations provide a new way to deal with state, which allows for flexibility not available in class-based languages. In IB state can be type-refined in subtypes. The combination of a purely IB style and type-refinement enables powerful idioms using multiple inheritance and state. To introduce IB to programmers we created Classless Java: an embedding of IB directly into Java. Classless Java uses annotation processing for code generation and relies on new features of Java 8 for interfaces. The code generation techniques used in Classless Java have interesting properties, including guarantees that the generated code is type-safe and good integration with IDEs. Usefulness of IB and Classless Java is shown with examples and case studies.
