You don't want to do that in Coldfusion - it is unnecessary and is actually a performance hit as well. Read up on 'duck typing' - Sean Corfield has a nice powerpoint that outlines this concept. You have to remember that Coldfusion does not enforce strict typing; Coldfusion is not Java!! The basic idea is that if you pass in a value (be it a string, query, object, whatever) and it works within your code, it is of the correct type (if it walks like a duck, quacks like a duck, it's a duck!). If you pass in a numeric value to a function that is expecting a string, it's going to work. If you pass in an object with properties x, y, and z to a function expecting an object with properties x, y, and z it's going to work. If you were to restrict your function to only accept objects with a type of cfc.exampleObj, you are unnecessarily restricting the possible input of your function as well as creating a performance loss by making your function check the object's type in the first place!
