Object Orientation

Object Orientation. James Brucker. Smalltalk. Ahead of its time: consistent design and rich library. Dynamic (like Lisp): variables have no specified type. The class structure is the type system. Everything is an object, including numbers. So somewhat lacking in efficiency.

Object orientation and object patterns

Object orientation and object patterns. Design failures. Rigidity Hard to modify functionality without major re-work (e.g. fixed strings in menu items) Fragility P(error) high after modification Immobility Code hard to re-use on other projects (often due to coupling) Viscosity of design

Object Orientation

Object Orientation. “Thinking” Object Oriented, Further Constraints, and Documentation. An Aside. To some of you, I imagine that some of C++’s syntax and structure may be pretty foreign, to say the least. In particular, some people have never worked (heavily) with OO before.

Object Orientation

Object Orientation. WHY: Try to model the data, not the tasks/procedures: Data change less often! Data is considered to be objects. Some more of the (claimed) benefits of using OOA&amp;D methods. Increased abstraction Encouragement of cyclic development ; easy to revisit early stages

Object Orientation

Object Orientation. Why We Do It. Typical “Early” Code. Often, when programming is taught, the majority of the focus is on learning to use basic data types, programming logic, and functions. Much of the program is often thrown into one main method, which might call one or two other functions.
