Name of construct
in [OOP]
|
From: Jens Winter on 23 Aug 2006 03:56 Hello, I'm looking for the name of a OO construct. It is used in jMock for example and looks like this: mockSubscriber.expects(once()).method("receive").with( eq(message) ); It is used to increase the readability of code. I think there is a term for such constructs. But I can't remember it. Ciao, Jens

I never heard of jMock, but this just looks like basic callback registration via something like the Observer pattern. ************* There is nothing wrong with me that could not be cured by a capful of Drano.

Hello H. S., What I meant was that the construct uses methods that can be concatenated. This way it is possible to for example initialize an object that has a hierarchical structure. An alternative sample to the above code could be something like this: Expectation expectation = new Expectation(); expectation.SetMethod("receive"); expectation.SetExpectedResult(message); mockSubscriber.AddExpectation(expectation, 1); Uhm, I think I will have to come up with another (better) example some time. :) Ciao, Jens

An alternative sample to the above code could be something like this: Expectation expectation = new Expectation(); expectation.SetMethod("receive"); expectation.SetExpectedResult(message); mockSubscriber.AddExpectation(expectation, 1); So, I don't think the term has something to do with callback or observer pattern. Uhm, I think I will have to come up with another (better) example some time. :) Ciao, Jens

I think "fluent interface" might be the answer you're looking for... http://www.martinfowler.com/bliki/FluentInterface.html Jens Winter wrote: > Hello H.
