<tip type="ColdFusion CFC Interface" author="Mark M">
To create pseudo Interfaces / Abstract Base Classes in a CFC in coldfusion, simply define your 
methods as per normal, except throw a standard exception as it's definition.

For example:
<cfthrow message="This method is virtual and cannot be called" 
               type="com.InterfaceMethodCalledException"
               detail="To call this method, it must first be implemented in a child 
               class of this base class."
               >


That way, if the method is called when it hasn't been defined it will throw an error.

Now you can use the concept of Interfaces with CFCs.
