摘要

异常安全强有力的保证:操作要么成功完成,要么抛出异常,使程序的状态与操作开始前完全一样。David Abrahams[1]上述强异常安全的定义来自c++世界,但它可以应用于任何语言。因为异常安全强保证在简化健壮软件的开发中起着中心作用,所以我们设计了一个能够捕捉其本质的类型系统。我们为类java语言提供了一个轻量级的类型系统,它通过向类型引入一个简单的修饰符来强制程序满足强保证。

Strong exception-safety for Java-like languages
"Exception-safety strong guarantee: The operation has either completed successfully or thrown an exception, leaving the program state exactly as it was before the operation started." David Abrahams [1] The above definition of strong exception-safety comes from the world of C++, but it can be applied to any language. Because the exception-safety strong guarantee plays a central role in easing the development of robust software, we have designed a type-system able to capture its essence. We present a lightweight type system for Java-like languages that, by introducing a simple modifier to types, enforces programs to satisfy the strong guarantee.
