摘要

本文试图解释面向对象的形式化如何提高异常处理系统的表达能力，以及如何简化异常处理系统的实现和使用。利用该方法，实现了一个用户友好、功能强大、可扩展和可重用的异常处理系统。描述了使用00L的这种系统的规格。一些经典的异常处理需求已经很容易实现，并且提出了新的功能，其中最重要的可能是用户能够重用和定制现有系统，以便在应用程序中提供特定的异常处理。该系统是用面向对象语言和Smalltalk. b>实现的

Improving exception handling with object-oriented programming

An attempt is made to explain how the object-oriented formalism can improve the expressive power of an exception handling system and how it can simplify its implementation and its utilization. Using the proposed approach, a user-friendly, powerful, extensible and reusable exception handling system has been implemented. A specification of such a system using an 00L is described. Several classical exception handling requirements have been easily implemented and new functionalities have been proposed, among which the most important may be the ability for users to reuse and customize the existing system in order to provide specific exception handling in application programs. The system has been implemented in the Lore object-oriented language and in Smalltalk.<>
