Re: whats the purpose of an objectFactory?

This is one more piece of code that has to be ran, >maintained, suck up processes, suck up memory, to explain Wouldn't >it be best to just keep it simple and call right to the CFC? It sounds to me like you're using CFCs more as code libraries and less as objects, or that your particular application(s) generally only use singletons (one instance of an object only), like an object that handles security. In these cases factories are next to useless - as you noted why would you want to write a factory to build one instance of an object? Factories build instances of objects for you. And more than that, they may build instances of different objects depending on the input you send to the factory when you request an instance. In the simpler case, elsewhere in this thread someone already pointed out the benefits of using a simple factory for instantiation of a single object type when you are creating lots of those objects - you consolidate initialization of the object in one place, simplifying your code and making maintenance easier. Consider a hypothetical situation... I work at a university. So I might have objects that represent Faculty, Staff, and Students, all inhieriting from a Person class. I could use the factory to decide for me whether I need to instantiate a Faculty, Staff, or Student at runtime, and to centralize that decision making activity for me. Another example would be a factory that creates instance of objects that wrap remote services.. If you had a class that generically implemented access to various kinds of remote data (XML files, CFCs, web services, etc). The implementation of those classes would be different for each type of call, but the interface - the properties and method definitions - would be the same. At runtime the application wouldn't need to care if it was holding a RemoteCallCFC or a RemoteCallWebService. A factory would determine which class was necessary, instantiate it, initialize it, and pass it back to the requesting program. ~| Create robust enterprise, web RIAs.

Re: ordering Poker hands
>I am building a poker applicaiton. > >Has anyone dealt with determining the value of a hand? > >I have the feeling I am making it even more complicated than necessary. Everybody seems to be advocating a database-based approach. I wouldn't try to assign a value to each hand at all, you need a function that compares hands similar to the way humans do. 1. tokenize the hand so you know what you're dealing with for 9-9-10-J-2 you have "a pair of 9s", "a single J", "a single 10", and a single "2" in that order for K-K-K-10-10 you have "a full house, K's over 10's" (one token) comparing those hands, the full house token beats the pair of 9's token. If you had 9-9-J-J-2 vs 9-9-J-J-3, you'd compare the tokens in order - pair of J's vs pair of J's are equal, so check the next token.. pair of 9's vs pair of 9's are equal so check the next token.. Single 3 beats single 2. I'd write a class with functions to compare two tokens and tell you which one is greater than the other, or if they're equal. Then I'd write individual functions to compare like tokens (ie so the class can tell that a K high flush beats a 7-high flush). You'll also obviously need a function to do the tokenization of the original hand. Then you just compare tokens in descending order to determine which hand is better. It actually sounds like a fun project. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:259625 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Embed an XML document into another?
I have an application that kicks around data about an event from function to function in an XML document. If I have an error I'm trapping with try/catch, I want to use wddx to serialize the cfcatch struct, parse it to XML, and embed it in the error element in my event XML. if I try: xError = xmlparse(replace(errorXml, 'wddxPacket', 'wddx-packet', 'ALL')); //Stops CF fromseeing a wddx packet "type" structInsert(xEvent.event.error, "wddx-packet", xError); I get: The XML node [#document] has type [DOCUMENT] which cannot be added to the content of an element. In order to get a node, not a document, if I replace: structInsert(xEvent.event.error, "wddx-packet", xError); with: structInsert(xEvent.event.error, "wddx-packet", x["wddx-packet"]); I get: WRONG_DOCUMENT_ERR: A node is used in a different document than the one that created it.

It's basically stored SQL loader which allows you to access an external text file as you would any read-only oracle table via SQL.
