Eiffel

(language)An object-oriented language produced by Bertrand Meyer in 1985. Eiffel has classes with multiple inheritance and repeated inheritance, deferred classes(like Smalltalk's abstract class), and clusters ofclasses. Objects can have both static types and dynamic types. The dynamic type must be a descendant of the static(declared) type. Dynamic binding resolves multiple inheritance clashes. It has flattened forms of classes, inwhich all of the inherited features are added at the samelevel and generic classes parametrised by type.

Other features are persistent objects, garbage collection,exception handling, foreign language interface. Classesmay be equipped with assertions (routine preconditions andpostconditions, class invariants) implementing the theory of"Design by Contract" and helping produce more reliablesoftware.

Eiffel is compiled to C. It comes with libraries containingseveral hundred classes: data structures and algorithms(EiffelBase), graphics and user interfaces (EiffelVision) andlanguage analysis (EiffelLex, EiffelParse).

The first release of Eiffel was release 1.4, introduced at thefirst OOPSLA in October 1986. The language proper was firstdescribed in a University of California, Santa Barbara reportdated September 1985.

Eiffel is available, with different libraries, from severalsources including Interactive Software Engineering, USA (ISEEiffel version 3.3); Sig Computer GmbH, Germany (Eiffel/S);and Tower, Inc., Austin (Tower Eiffel).

The language definition is administered by an openorganisation, the Nonprofit International Consortium forEiffel (NICE). There is a standard kernel library.

An Eiffel source checker and compiler front-end isavailable.

Latest version: 4.2, as of 1998-10-28.

Latest version: ISE Eiffel version 3.3.

Eiffel

An object-oriented programming language from Eiffel Software Inc., Goleta, CA (www.eiffel.com). Developed in 1985 by Bertrand Meyer, it evolved into an IDE product family for Windows, Unix, Linux, VMS, Mac OS X, as well as embedded systems. Full integration with Visual Studio .NET is available. The Eiffel compiler generates C code, which can be modified and recompiled with a C compiler. Originally offered by Interactive Software Engineering Inc., the company renamed itself Eiffel Software in 2002.
