摘要

就像其他软件一样，Java概要文件在使用和发展了一段时间后也会从重构中受益。本文提出了对Java实时规范(RTSJ)和安全关键Java (SCJ)配置文件(JSR-302)的重构。它突出了核心概念，并使其成为建议的SCJ水平的合适基础。正在进行的指定SCJ概要文件的工作建立在RTSJ子类的基础上。这激发了我们对重构方法的兴趣。它首先从核心包中提取规范的公共内核，该内核只定义接口。然后，就可以用它的三个层次重构SCJ和RTSJ，这样每个概要文件都在一个单独的包中。这种重构产生了更清晰的类层次结构，没有多余的方法，定义良好的SCJ级别，消除了像@SCJAllowed这样的SCJ注释，从而使配置文件更容易被应用程序开发人员和学生理解和使用。

Refactoring Real-Time Java Profiles

Just like other software, Java profiles benefits from refactoring when they have been used and have evolved for some time. This paper presents a refactoring of the Real-Time Specification for Java (RTSJ) and the Safety Critical Java (SCJ) profile (JSR-302). It highlights core concepts and makes it a suitable foundation for the proposed levels of SCJ. The ongoing work of specifying the SCJ profile builds on sub classing of RTSJ. This spurred our interest in a refactoring approach. It starts by extracting the common kernel of the specifications in a core package, which defines interfaces only. It is then possible to refactor SCJ with its three levels and RTSJ in such a way that each profile is in a separate package. This refactoring results in cleaner class hierarchies with no superfluous methods, well defined SCJ levels, elimination of SCJ annotations like @SCJAllowed, thus making the profiles easier to comprehend and use for application developers and students.
