Dave, ColdFusion is soooo dynamic that when you talk about things that "relate" to other languages, it is more in philosophy than practice. When I say "Constant" I don't mean a value that never changes, I mean a value that should not be changed by the user. I mean a value that does not change from instance to instance (basically a static value). Like wise, when you say a "public" or "private" method - since those can so easily be hacked - it is only a philosophy, a "suggestion" - a contract the user makes with the application.
It's all philosophy, don't worry about how things actually port from one language to another. ......................

Since CF doesn't have constants, you have to be careful about making analogies with languages that do. Constants can't be changed. The closest thing, functionally speaking, to creating a public constant within a class in CF is to create a private member variable with a public accessor.
