Michael: I'll admit that I don't have years of OO experience behind me, but in my experience I've found that many of the applications I've designed/built share a very common paradigm: objects that require a line-item view (e.g. lists and search results) and a zoomed-in or "detailed" view (often used for full view of a single object or an edit/modify page of that object).
With that assumption, I think it makes the most sense to reserve object instantiation for those full views of your object while creating other CFC's that simply build queries for search results. I suppose the better question to ask is - why would I need all the glorious details and methods of a particular object if all I can really do in a line-item sort of view is click on it? Again, I'm not an OO expert by any means, so if someone out there can enlighten us further, I'd look forward to it. I just try to use business (or more specifically end-user) goals to drive the design. -Rich -----Original Message----- From: Pacella, Michael [mailto:[EMAIL PROTECTED] Sent: Thursday, June 26, 2003 11:37 AM To: CF-Talk Subject: CFC performance difficulties Has anyone experienced slow downs when passing around several CFCs as objects ? Here's the problem we have run in to: To encapsulate information about all of the Campuses in our database, a CFC was created to act sort of like a Java object representing campus (complete with properties such as campusName, campusCode, campusBeginDate, campusContact, etc.. -- and settors and gettors to retrieve them)... Another CFC was created to access the database, performing functionality such as "search". Search would query the DB, and then step thru the results, creating Campus CFC objects for EACH campus returned. The end result of the function would be a Structure whose Keys were the CampusCode and whose Value were the actual, aforementioned Campus CFC object. Passing around over 100 of these CFC objects encapsulated in a Structure causes a massive performance hit....Using GetTickCount(), it was determined that simply writing a query and looping through it took about 27 milliseconds. Whereas, creating this structure of Campus CFCs, looping through that and having an actual OO programmatic concept took about 563 milliseconds. That seems a little bit excessive. The question is, (1) am I misconstruing the power of CFCs (2) can/have they been implemented in a similar fashion (3) was it intended for several to be encapsulated in structures (which old Java guys might look at as Hashtables whose values are Objects)... Any insight here would be extremely helpful -- Thanks ! <http://webforums.macromedia.com/coldfusion/messageview.cfm?catid=3&thre adid =643548> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Host with the leader in ColdFusion hosting.
