Eiffel in a Nutshell Here is what everyone needs to know about Eiffel. You'll find lots more details in the rest of these Web pages. For the busiest of the busiest there is also the 1-minute summary After reading the present page you can use the complete Eiffel page to find links to many more detailed entries. What is Eiffel? Good question. Answering "an object-oriented language " is correct, but only part of the story. Eiffel is the only O-O language that also includes a comprehensive approach to software construction: a method , and an environment (EiffelStudio). The language itself is not just a programming language but also covers analysis, design and implementation. What are the goals of Eiffel? Eiffel pursues four major goals: To give you a competitive edge by enabling you to get your software out fast. To lower your maintenance and support costs by letting you produce bug-free software software that works the first time around. To allow you to react quickly to market demands by producing software that is easy to change and extend in response to user requests. To preserve your investment by giving you robust software that can be reused in many different developments.

Ostroff , Department of Computer Science, York University, Canada Richard F. Paige , Department of Computer Science, University of York, York, U.K. REFEREED ARTICLE PDF Version Abstract The Simple Concurrent Object-Oriented Programming (SCOOP) mechanism introduces inter-object concurrency to the Eiffel language, via addition of one new keyword, separate. We describe a general tool that takes a Eiffel program that uses the separate keyword and translates it into an Eiffel multi-threaded program that uses the Eiffel THREAD class. The resulting code is thereafter compatible with EiffelStudio and any other Eiffel compiler that provides the THREAD class. 1 INTRODUCTION AND BACKGROUND Many mechanisms exist for introducing concurrency into object-oriented (OO) programming languages. These approaches support the use of multiple, perhaps distributed processors, each of which may be executing multiple processes. Different techniques are provided with the languages to support synchronisation, interruption, mutually exclusive access to object state, and atomic execution of routines. PROCESS that could be used to introduce new threads of execution. Jalloul [7] extends Eiffel by providing new language features for implementing critical regions and conditional critical regions; these new features are in turn implemented in a kernel sitting atop PVM. Variants of Smalltalk have been proposed [12, 9] for multi-threading. Similarly, C++ extensions such as Parallel-C++ [8] exist for parallel, distributed, and concurrent execution.

Object-Oriented Language: Eiffel See also Eiffel / Libraries Intro Eiffel is a pure, statically typed OO language. Eiffel has built-in support for Design By Contract. Why Eiffel? Eiffel is arguably the best commercial object-oriented language available today (Jim Rumbaugh). We settled on Eiffel because it provides the right paradigms to address the construction of large, high-quality object oriented software systems and is quite easy to master (authors of Design Patterns and Contracts). Eiffel is more than a language; it is a framework for thinking about, designing and implementing object-oriented software (Richard Wiener). Contents Start here Fun Central Sites Related Sites ...
