Not that I've worked with CFC's as of yet, but there is a 3rd way.
Write a single pair of set / get functions into a "core" cfc and then have
all your other cfc's extend the core cfc, so that for any given component
you know that you can use #mycfc.getValue("propertyname")# to return
whatever that property happens to be whether it's a string, struct, array or
another CFC. For any property which needs special handling, write an
additional get / set method, then in the core get / set method check for the
existance of a get or set method specifically for that property, such as:
<cffunction name="getValue" ouptut="false">
<cfargument name="propertyname" type="string" required="true">
<cfif isdefined("this.get_" & propertyname)>
<cfreturn evaluate("this.get_#propertyname#()")>
<cfelse>
<cfreturn this[propertyname]>
</cfif>
</cffunction>
And of course, use a similar set function. This way you only have to write
getters and setters for properties that require special internal handling by
the CFC for business logic or technical reasons.
Ahhh the magic of OO. :)
