Does ColdFusion offer a mechanism for splitting CFCs into multiple files? I am NOT talking about extension, I am talking about splitting the SAME CFC into multiple files; the same way C# allows for "partial" classes. The reason for this is because I am using T4 to generate a bunch of CFCs and I want to be able to tag functionality onto the generated CFC by doing so in another file. I want to do this in a way that doesn't violate the Open-Closed Principle.
No, sorry. A limitation of the language, I'm afraid. A CFC is a single file.
I mean, of course, you could bastardize it somehow. You could have fragments that are wrapped in a cfcomponent tag as part of some kind of build process, but I'm pretty sure that's not what you're looking for here.
