Passing ColdFusion Arrays By Reference

I just run the following test: <cfset javaArray = CreateObject("java", "java.util.ArrayList").Init()/> <cfset regArray = arrayNew(1)> <cfset arrayResize(regArray,100000)> <!--- <cfset arrayResize(javaArray,100000)> ---> <cftimer label="Test Java Array" type="outline">   <cfloop index="m" from="1" to="100000" step="1">     <cfset javaArray[m] = m>   </cfloop> </cftimer> <cftimer label="Test ColdFusion Array" type="outline">   <cfloop index="k" from="1" to="100000" step="1">     <cfset regArray[k] = k>   </cfloop> </cftimer> And a) CF array runs faster due to the benefits of the resize (otherwise the run time is similar) b) your version of the array is not supported by the resize, so your array is not 100% like regular CF array with additional benefit of passing by reference. One would now have to check a lot more about your array version to figure out what it supports and what it doesn't support.
