Issues with Exception Handling in Object-Oriented Systems

چکیده
The goals of exception handling mechanisms are to make programs more reliable and robust. The integration of exception handling mechanisms with object-oriented languages raises some unique issues. The requirements of exception handling often conflict with some of the goals of object-oriented designs, such as supporting design evolution, functional specialization, and abstraction for implementation transparency. This paper demonstrates these conflicts, illustrates that the use of exception handling in object-oriented systems poses potential pitfalls, and suggests that their resolution is one of the first steps necessary to make exception handling robust in object-oriented designs and languages.

A comparative study of exception handling mechanisms for building dependable object-oriented software
Modern object-oriented systems have to cope with an increasing number of exceptional conditions and incorporate fault tolerance into systems' activities in order to meet dependability-related requirements. An exception handling mechanism is one of the most important schemes for detecting and recovering errors, and for structuring fault-tolerant activities in a system. The mechanisms that were i...
متن کاملImproving exception handling with object-oriented programming
The aim of this paper1 is to show and 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. Object-oriented design allows implementors to solve easily many classical exception handling issues such as creating user-defined exceptions, passing arguments from signalers to handler...
متن کاملImplementing Coordinated Exception Handling for Distributed Object-Oriented Systems with AspectJ
Exception handling is a very popular technique for incorporating fault tolerance into software systems. However, its use for structuring concurrent, distributed systems is hindered by the fact that the exception handling models of many mainstream object-oriented programming languages are sequential. In this paper we present an aspect-based framework for incorporating concurrent exception handli...

متن کاملA Fully Object-Oriented Exception Handling System: Rationale and Smalltalk Implementation
This paper motivates and presents the specification and the implementation of an exception handling system for an dynamically typed object-oriented language. A full object-oriented representation of exceptions and handlers, a meta-object protocol to handle using either termination or resumption makes the system powerful as well as extendible and solves various exception handling issues. Three k...
