Algorithmic Abstraction in Object-Oriented Languages
The abstraction gap between algorithms and procedures causes numerous duplicate eeorts in implementing the same algorithms as well as apparent under-use of many eecient algorithms. A solution to this problem is to realize algorithmic abstraction at the programming language level in addition to data abstraction. In this paper, we rst discuss the two conditions for a programming language to suppo...

متن کاملAbstraction in an Object - Oriented Analysis Method
The recent interest in object-oriented analysis has resulted in the introduction of abstraction in the analysis phase of information systems development life cycle. Abstraction has been proven to be a powerful object-oriented construct through which software complexity can be reduced and software productivity can be improved. Our main aim in this paper is to provide the support of abstraction f...
متن کاملSather Iters: Object-oriented Iteration Abstraction
Sather iters are a powerful new way to encapsulate iteration. We argue that such iteration abstractions belong in a class' interface on an equal footing with its routines. Sather iters were derived from CLU iterators but are much more exible and better suited for object-oriented programming. We motivate and describe the construct along with several simple examples. We compare it with iteration ...
متن کاملProgram Development in Java - Abstraction, Specification, and Object-Oriented Design
Written by a world-renowned expert on programming methodology, and the winner of the 2008 Turing Award,Ð’Â this book shows how to build production-quality programs--programs that are reliable, easy to maintain, and quick to modify. Its emphasis is on modular program construction: how to get the modules right and how to organize a program as a collection of modules. The book presents a methodolo...
