| NEXTSTEP to OPENSTEP Changes Overview: Portability - a layer of operating system and hardware independence. - NSString, insulates your code from the different character encodings . Distributed Objects - easier than ever - share information between processes without using operating system calls. Simplified archiving - same for DO as for local. Everything is an Object - events, exceptions, colors, screens, and DPSContexts are now objects. - It also provides better encapsulation and future extensibility. Truly Internationalized Applications - write truly internationalized code, code that will work with any writing system supported by the Unicode standard. New Memory Management - reference counting scheme - OPENSTEP API works the same remotely as it does locally. Cleaner, Simpler API -better compile-time type checking. -methods that used to return self by convention now return void. - classes with more complex APIs have been simplified. |
