"Working with Objects" by Andy:
Object Orientation is supposed to benefit developers by allowing us to create re-usable code. However, the reality is that in the real world it is very difficult to find the time required to do the sort of detailed analysis that is prescribed by all the design textbooks. In this session Andy outlines some simple rules for creating classes that, when followed, will help you to improve your own class design and enable you to create more flexible and more widely re-usable code. He also discusses why and when you should be making use of Delegation, Aggregation and Composition and illustrates how to use these techniques in your daily work
"Programming To Interface" by Marcia and Andy:
The idea of programming to interface rather than implementation is a concept that has been around for a while now. It is a phrase that is over-used and often misinterpreted. Programming to interface (or, more accurately, to Public Interface) has nothing to do with user interface. Rather, it refers to the set of properties, events and methods exposed by an object to its environment. This interface forms the basis of the contract that governs the interaction between objects. In an object oriented environment this has some very important implications, and consequences, as this session illustrates.
- Anything else people want to talk about.
Hope to see you there.
