Ok, that makes sense. So is there an instanceof method in CF or something similar to tell you what class was used to create your object.
Also, can you create an interface with CFC's, and then implement that interface with another class?

Actually, being able to use one variable to store different objects can be very useful, and is commonly done in OO languages. However, these tend not to be just any two different objects, but objects that either inherit from the same base class or implement the same interface. For example, you might have a bunch of objects that are sortable. You might write a single interface, ISortable, then write functionality in each class to implement how ISortable works for that specific object type. Then, if you have an array of objects, all of which implement ISortable, you could sort them without worrying about what kind of objects they are exactly. This is a big deal in C# now, with the addition of generics - type-safe collections of various kinds. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:239838 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
