Coldfusion Design Patterns

Singletons are perhaps one of the most simple Design Patterns. For those who don’t know sigletons are a class that can only have one instance. They can be thought of as a glorified global variable - but are a lot more useful.

As I make my way through Head First Design Patterns, which I am starting to agree is a “must” on a developer’s bookshelf, I decided I would work out some of the exercises in ColdFusion code. It is geared towards Java, but the principles carry over into OOP practices in ColdFusion as well.

“As ColdFusion developers, we tend to build applications based on pages that display information and queries to retrieve information and save information. We tend to think solely of how we are going to implement the code required to perform a certain function. Many times we are not able to consider the commonality of a certain problem and whether an already established design exists somewhere.

Often we are not able to set aside time to do this research. Knowing and utilizing design patterns allows us to think in a common language, with an ever-expanding library of well thought out solutions to consider when architecting an application. Recognition of these patterns in our everyday jobs can make us significantly more productive and seem even smarter than we are.”
