Yes, that's a pretty good way to implement it (so I'd say that you do,
indeed, "get" CFCs). In fact, you could have a method that gets all the
data, declared access="private", and then in each of your
'getSomething()' methods, you test whether the data is already in cache
and, if not, call the private 'getAllData()' method to load it:
<cfcomponent>
<cfset isCached = false>
<cffunction name="getAllData" access="private">
... load all the data into some instance variable ...
<cfset isCached = true>
</cffunction>
<cffunction name="getSomething">
<cfif not isCached>
<cfset getAllData(...)>
</cfif>
<cfreturn myCache.something>
</cffunction>
</cfcomponent>
