So, I'm relatively new to OO in ColdFusion, and I'm banging my head against one
issue in particular. Let's say I've got a DAO or Gateway object in my
APPLICATION scope that needs to return a collection of beans, I'm having
trouble understanding the need to VAR scope all internally used variables when
I've got a dynamic number of objects being returned. That's not very clear, so
let's say this is the function in question:
<cffunction name="getContacts" access="public" returntype="Contact[]">
<cfset returnArray = ArrayNew()>
<cfset q_Contacts = "">
<cfquery name="q_Contacts">
SELECT *
FROM Contacts
</cfquery>
<cfloop query="q_Contacts">
<cfset thisContact = createObject('component', 'Contact').init(...insert
init info here...)>
<cfset ArrayAppend(returnArray, thisContact)>
</cfloop>
<cfreturn returnArray>
</cffunction>
So, my concern is with the inability to create the Contact objects in the VAR
scope since I don't know how many I'll be creating before hand. If I do it
like this (i.e. without the VAR on the createObject), am I setting myself up
problems? If so, how should I handle this?
Thanks again, and I hope it's not to ridiculous a question.
