I don't agree. If you create a CFC "testComponent" that returns an
array of the integers 1-100, then run this code:
============================
<cfscript>
myObj = createObject("component", "test.testComponent");
</cfscript>
<cfloop from="1" to="2" index="j">
<cfset "request.thisArray#j#" = myObj.getArray()>
</cfloop>
<cfset request.thisArray2[1] = "foo">
<cfdump var="#request.thisArray1#">
<cfdump var="#request.thisArray2#">
=================================
request.thisArray2[1] is "foo", while request.thisArray1[1] remains 1.
Also, the 1000-iteration loop caused my memory monitor to drop
several K.
Seems like it's creating copies of the array, not pointers at all. What
am I missing?
For the self-testers, here's the little CFC I threw together:
========= Begin testComponent.cfc ===========
<cfcomponent displayname="myTest">
<cffunction name="getArray">
<cfset myArray = arrayNew(1)>
<cfloop from="1" to="100" index="i">
<cfset myArray[i] = "String " & i>
</cfloop>
<cfreturn myArray>
</cffunction>
</cfcomponent>
========= End testComponent.cfc ===========
