And luckily getMetaData has been fixed in ColdFusion 8 so it no longer creates the object :-)

This also means that you can cache your own metadata in the metadata struct if you care to. Like, for example, the results of instanceOf calls, so repeated calls with the same type don't have to scan the tree. Exception handling is typically an expensive operation, because performance is less important that assisting in recovery and/or debugging (if it's checked or unchecked). Java has this characteristic, and since CF uses the Java exception handling mechanism (plus a wrapper), CF has the same issues/benefits. cheers, barneyb On 6/6/07, Brian Kotek <[EMAIL PROTECTED]> wrote: > Actually I'm quite sure that a try/catch block would be much faster than > calling getMetaData(), especially for CFCs with more than 1 or 2 levels of > inheritance. > -- Barney Boisvert [EMAIL PROTECTED] http://www.barneyb.com/ Got Gmail?
