The project has the concept of a Directory and a VirtualDirectory was a directory which wasn’t associated with a directory in the file system. In the project, all classes had the prefix Sapphire since it was a bundle included in another application and had to make sure there was never a class conflict. I have run into cases where this borders on ridiculous if one wants the class name to define what it actually does without ambiguity. In Java, the package name gets longer where as in Objective-C the class name gets longer. Then take that new network connection and add new specific case to it, making a new class. Now, take the above scenario, and add another type of network connection. Since Objective-C does not have namespaces, I would have to name these NetworkConnection and DatabaseConnection. This is possible in Java because the actual class names are .Connection and .Connection.

Inside those packages, especially if the Connection class was internal to the package only, I could name both classes Connection without any concern and the code inside the package would immediately understand what Connection actually meant. Inside each package, I would likely have a Connection class, which has completely different meanings within the network and database packages. If I were designing an application which communicated on a network as well as talked to a database, I would split the two pieces into separate segments, or in Java, packages. This is due to the fact that without a concept of namespace, Objective-C cannot have two classes with the same name, regardless of whether the classes are public or not. On the mac side of things, every class under the sun seemed to start with NS, such as NSString, and confusion is added when on the iOS side, several classes start with UI, such as UIView. As a result, classes have a prefix, such as Apple’s common NS and UI prefixes. The other parts can be found here:įor one who has programmed in other object oriented languages, Objective-C stands out with its complete lack of namespace.

This is the last is a series of blog posts I’m writing on things that Objective-C can learn from Java.
