  Eiffel Object Model
Eiffel is an object-oriented language designed for the specification, design implementation and modification of large applications and reusable components.
An Eiffel class is an implementation of an abstract data type i.e., a class describes the operations available to the type and formal properties of those operations.
Eiffel supports both late and early binding (in general this is true, however it depends on the implementation).

 Eiffel Tower - Tour Eiffel, Paris
Eiffel knew and publicly acknowledged this influence; he was no stranger to the United States, having designed the wrought-iron pylon inside Frederic Bartholdi's Statue of Liberty in 1885.
Eiffel was the leading European authority on the aerodynamics of high frames (he wrote "The Resistance of the Air" in 1913).
In the construction of the Eiffel Tower, the curve of the base pylons was precisely calculated so that the bending and shearing forces of the wind were progressively transformed into forces of compression, which the bents could withstand more effectively.

 comp.lang.eiffel Frequently Asked Questions (FAQ)
It includes an Eiffel to C compiler, an Eiffel to Java bytecode compiler, a documentation tool, a pretty printer, etc. The compiler uses an innovative strategy involving whole system analysis which allows compilation to be often faster than the incremental compilation of traditional compilers.
Other Eiffel compilers are worth mentioning although they may be either not supported any more, or an older version, or at an early stage of development so that their implementation of the language may be far from complete.
Eiffel is still a relatively new language, and there have been a number of changes to its definition.

 Wikinfo | Eiffel programming language   (Site not responding. Last check: 2007-10-16)
Eiffel is strongly statically typed, with automatic memory management (typically implemented by garbage collection).
Eiffel intentionally limits stylistic expression, providing few means for clever coding tricks or coding techniques intended as optimization hints to the compiler.
Eiffel tends to be quite closely connected to C; three of the four Eiffel compilers produce C code rather than object code.

 Eiffel Language
Eiffel is also 600USD for the pro version, and 2000USD for the enterprise version, unless you're using non-Linux Unix, at which point it becomes 3000/5000.
So Eiffel uses a scheme called wait by necessity which says that commands can be dispatched asynchronously, and we just need to maintain an invariant: before a query is executed on a remote object, all of our previous commands must have already been processed, and in the same order they were issued.
Eiffel Software, Inc. http://www.eiffel.com/ As of April 5th, 2006, the compiler is released under a dual GPL/non-free license (in the same style and the same buisness model as the QT library)

 SmartEiffel, the GNU Eiffel Compiler, Tools and Libraries   (Site not responding. Last check: 2007-10-16)
Eiffel is a pure object-oriented language aimed at the writing of software components that are easy to read, maintain, test, extend and reuse.
As the compiler translates Eiffel code either to C or Java bytecode, it can be used to write programs that run on virtually any platform for which an ANSI C compiler or a Java virtual machine exist.
As other Eiffel compiler writers declare to be compromised with this standard (although it is far from being implemented at time being), writing portable across Eiffel compilers code is going to be increasingly difficult.

 ISE Eiffel in a nutshell
Eiffel's openness to the outside world, enabling it to serve a glue between software elements that may be written in many different languages (such as C or C++) besides those written in Eiffel.
With Eiffel you can quickly produce a basic version of a system, reliable and efficient, put it into users' hands early (while the competition is still trying to produce a bug-free "prototype"), and come up with new releases rapidly, all the time maintaining the standards of robustness that are the hallmark of the approach.
Eiffel recognition was given a large boost by the appearance in 1988 of the book Object-Oriented Software Construction by Bertrand Meyer, which quickly became the best-selling title in the field and was translated into eight foreign languages; the book used Eiffel as the natural vehicle to introduce concepts of object technology and Design by Contract.

 Eiffel (programming language) - Wikipedia, the free encyclopedia
Eiffel provides a straightforward interface to C routines, including support for "inline C" (writing the body of an Eiffel routine in C, typically for short machine-level operations).
Although there is no direct connection between Eiffel and C, all of the current Eiffel compilers except one (Visual Eiffel) output C source code as an intermediate language, to submit to a C compiler, for optimizing and portability.

 Why your next project should use ISE Eiffel
Eiffel and the associated Business Object Notation approach to analysis and design accommodate them naturally, by providing a single conceptual framework from the beginning to the end of the process.
Eiffel is unique in helping you for all of these tasks, without ever introducing the impedance mismatches that characterize other approaches.
This also makes Eiffel one of the most open environments around; in contrast to the self-centered view that predominates in Smalltalk, Eiffel software is born with a sociable attitude, ready to interface with all kinds of other software written in C or other languages.

 Object-Oriented Software Engineering with Eiffel
In the software engineering domain, Eiffel is also the name of an object-oriented language that emphasizes the design and construction of large, high-quality softwares by assembling reusable software components, called classes, that serve as templates to make objects.
Beyond classes (on which modularity is based), Eiffel offers multiple inheritance, polymorphism, static typing and dynamic binding, genericity, garbage collection, a disciplined exception mechanism, and systematic use of assertions to improve software correctness in the context of programming by contract.
Finally, Chapter 9 shows how Eiffel can be used as an enabling technology to master a very complex problem: the building of a parallel linear algebra library (Paladin) that allows an application programmer to use distributed computing systems in a transparent way.

 Eiffel
Eiffel is an object-oriented language developed by Bertrand Meyer in the early 1980s.
