Abstract

This position paper shows how Ada 95 exceptions have been used in a prototype implementation of a transaction support in order to provide more elaborate exception handling. The paper summarizes the open multithreaded transaction model, which is a transaction model suitable for concurrent programming languages, and analyzes the exception mechanism provided by the Ada 95 programming language. Different interfaces to the transaction support for the application programmer are presented, and the problems encountered during implementation of the prototype with respect to exception handling are discussed.

Ada (programming language)

Ada is a structured, statically typed, imperative, and object-oriented high-level programming language, inspired by Pascal and other languages. It has built-in language support for design by contract (DbC), extremely strong typing, explicit concurrency, tasks, synchronous message passing, protected objects, and non-determinism. Ada improves code safety and maintainability by using the compiler to find errors in favor of runtime errors.

Exception handling

In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program. In general, an exception breaks the normal flow of execution and executes a pre-registered exception handler; the details of how this is done depend on whether it is a hardware or software exception and how the software exception is implemented.

Comparison of programming languages

Programming languages are used for controlling the behavior of a machine (often a computer). Like natural languages, programming languages follow rules for syntax and semantics. There are thousands of programming languages and new ones are created every year. Few languages ever become sufficiently popular that they are used by more than a few people, but professional programmers may use dozens of languages in a career. Most programming languages are not standardized by an international (or national) standard, even widely used ones, such as Perl or Standard ML (despite the name).
