Re: [Esug-list] Nested Degenerate Convenience Methods

I agree with Andres about calling it a convenience method (and also not calling it a pattern), but is this not also an example of currying?

I would call that code an example of "convenience methods". In C, those things would likely be implemented in terms of "macros". The term "pattern" is overloaded, I wouldn't use it here.

Re: [Esug-list] Nested Degenerate Convenience Methods

Hi Sean, I'm using "implicit default" or "implicit argument" for the chains of less and less terse methods that eventually call the fully-explicit canonic one. There is a related idiom where the explicit argument is a block, and the implicit version either results in a sentinel value or signals an exception, e.g. ifAbsent/ifNone. This one I call "default case handler". In either case, I'm not convinced the name is that clear, so if you get by a nice one, I'm interested. > On 01 Apr 2015, at 18:49, Sean P.

Nested Degenerate Convenience Methods

Is there a name for the following pattern? doSomething: arg1 ^ self doSomething: arg1 ifA: arg2Default doSomething: arg1 ifA: arg2 ^ self doSomething: arg1 ifA: arg2 ifB: arg3Default ----- Cheers, Sean -- View this message in context: http://forum.world.st/Nested-Degenerate-Convenience-Methods-tp4816719.html Sent from the ESUG mailing list archive at Nabble.com.
