Overkill? Because it's more flexible, or because it's less code?
Here's a reimplemented instanceOf method (the only change is the new
predicate on line 9). Definitely simpler than adding three new
methods to your classes, and then adding more code to your init method
to use them. Especially since you'll probably need the instanceOf
method anyway for doing superclass checking.
<cffunction name="instanceOf" access="public" output="false"
returntype="boolean"
hint="I return whether this object is an instance of the specified
type">
<cfargument name="type" type="string" required="true" />
<cfset var md = getMetaData() />
<cfset var curr = md />
<cfif NOT structKeyExists(md, "instanceOf_" & type)>
<cfset md["instanceOf_" & type] = false />
<cfloop condition="true">
<cfif curr.name EQ type OR ( structKeyExists(curr,
"implements")
AND listFindNoCase(curr.implements, type) GT 0 )>
<cfset md["instanceOf_" & type] = true />
<cfbreak />
</cfif>
<cfif NOT structKeyExists(curr, "extends")>
<cfbreak />
</cfif>
<cfset curr = curr.extends />
</cfloop>
</cfif>
<cfreturn md["instanceOf_" & type] />
</cffunction>
