Designing Repeat Patterns-A Closer Look

As a pre-cursor to design patterns in the previous article in this series I looked at common signs to over engineering your design by forcing a design pattern that doesn’t fit. One important point I made was not starting with a design pattern and opting to refactor to one when you know it’s necessary.

Adapters, Bridges, Composites and Façade’s are good examples. Behavioral, If the primary concern is how you access objects, perform operations on them and otherwise interact with them consider patterns like the Command, Iterator, Observer, Strategy and Visitor. It should be noted that the list above is far from exhaustive. Just an example of what you might be looking for.
