My original experiments with this architecture were done using a model So I decided to leave out inheritance as a built-in I didn't like the way Simula I or Simula 67 did inheritance (though I thought Nygaard and Dahl were just tremendous thinkers andĭesigners). Term "genericity" for dealing with generic behaviors in a ![]() Isn't quite valid, since it really comes from the nomenclature ofįunctions, and I wanted quite a bit more than functions. "polymorphism" was imposed much later (I think by Peter Wegner) and it These, and that these would be very very useful. My math background made me realize that each object could have several algebras associated with it, and there could be families of This out because I really thought of all these symbols as names for Would be just another message token (it took me quite a while to think I realized that theĬell/whole-computer metaphor would get rid of data, and that "<-" The B5000 almost did this via its almost unbelievable HW architecture. Messaging came at the very beginning - it took a while to see how toĭo messaging in a programming language efficiently enough to be I thought of objects being like biological cells and/or individual computers on a network, only able to communicate with messages (so The original conception of it had the following parts. ![]() Said: "It's object-oriented programming". It was probably in 1967 when someone asked me what I was doing, and I The design for the ARPAnet, the Burroughs B5000, and my background inīiology and Mathematics, I thought of an architecture for programming. When and where was the term "object-oriented" used first?Īt Utah sometime after Nov 66 when, influenced by Sketchpad, Simula, You put more emphasis on "messaging" - but I still would likeįor the records, my tutorial page, and further distributionĪnd publication could you please explain: (like "inheritance, polymorphism and encapsulation"), but Several reports about what you might have said in this regard With your definition or description of that term. Unfortunately, it is difficult to find a web page or source "object-oriented" in "ISO/IEC 2382-15", and you, because, The only two sources I consider to be "authoritative"Īre the International Standards Organization, which defines "object-oriented programming" for my tutorial page on the I would like to have some authoritative word on the term ![]() Sorry for the delay but I was on vacation.Īt 6:27 PM +0200 7/17/03, Stefan Ram wrote: There are possibly other systems in which this is possible, but I'm not aware of them.ĭate: Wed, 09:33:31 -0800 To: Stefan Ram [removed for Whether you're a professional tradesperson or a DIY enthusiast, Toolstop has the Allen key set you need to get the job done.OOP to me means only messaging, local retention and protection and hiding of state-process, and extreme late-binding of all things. Our sets offer a variety of sizes and styles to suit all needs, from basic sets with a few sizes to comprehensive sets with dozens of different keys. They are an essential tool for many trades and DIY projects, from assembling furniture to repairing bicycles.Īt Toolstop, we stock a wide range of Allen key sets from leading brands, including Sealey, and Stanley. Allen keys, also known as hex keys, are small, L-shaped tools used to drive bolts and screws with hexagonal sockets. ![]()
