So, I got a data store in my code that I'm loading in a function. In that store I want to use the each method to append each record to the body of a panel in a certain format. What I'm trying to figure out is how to use this "each" method. Has anyone ever had to use it before? I'm relatively new to functions and programming in general s...
I have a Python class C which should have two pseudo-dicts a and b. The term pseudo-dicts means that the dictionaries don't actually exist and that they are “recomputed” each time a key is accessed. In pseudocode this would look like this: class C: def a.__getitem__(self, key): return 'a' def b.__getitem__(self, key): ...

Is it possible to prohibit an instance of a class from calling a shared/static method? For example: I want to allow this: ClassName.MethodOne() But I want to disallow this: Dim A As New ClassName A.MethodOne() The reason this is desirable is that in this case it is semantically confusing if an instance can call the method. ...
Hello, I have been researching Javascript performance. I've learned that when accessing more than once, it is usually best to copy closure variables and class members into local scope to speed things up. For example: var i = 100; var doSomething = function () { var localI = i; // do something with localI a bunch of times v...
Hi, I have a CoreData model in my iPhone app, which is linked to a SQL Database with more than 50k records. When I generate the records classes, Xcode uses the @dynamic directive for properties. I have a property named "ISFAV", NSNumber type (CoreData does not use BOOL or Integer, it uses object types). Being short, I change the ISFAV pr...

My experience on the other hand is that S4 implementations often perform worse and cause a lot m...

C# methods in interfaces are declared without using the virtual keyword, and overridden in the derived class without using the override keyword. Is there a reason for this? I assume that it is just a language convenience, and obviously the CLR knows how to handle this under the covers (methods are not virtual by default), but are there...

After some Google searching (and winding up here to an unrelated question) I wondered if an...
