摘要

动态软件更新可以使正在运行的程序在执行时得到更新。在本文中,建立了一个简单的形式化系统,目的是了解更新类的底层基础,以便了解如何最好地构建可靠的可更新程序。更新演算是为O-O软件构建的,具有精确的数学语义。它是轻量级Java核心演算的扩展,支持类似于编程语言Java和c++的更新技术。微积分还展示了可以动态进行哪些更新。在论文的最后,我们证明了这些更新是类型安全的

Formalizing Class Dynamic Software Updating
Dynamic software updating enables running programs to be updated while executing. In this paper, a simple formal system is established with the goal of understanding the underlying foundations of updating classes, for the purpose of understanding how to best build reliable updatable programs. The update calculus is built for O-O software with a precise mathematical semantics. It is formulated as an extension of a core calculus for Featherweight Java, and supports updating technology similar to that of the programming language Java and C++. The calculus also presents what kind of update can be made dynamically. At the end of the paper, we proof that these update is type safety
