RE: [CFCDev] Facade - how to?

Title: Job Opportunities

Nando,   I am writing a set of components that can be extended, these abstract classes have the basic functionality required, which can then be extended using objects very straight forward.   The problem I have is that I have a situation where I have the ability of multiple sign ins to a system, this system is company based. So when someone logs into this application they can be from any company that is setup in the system, now if I extend these components ti give each company the functionality required for this particular task, and if we setup a company that looks for that object if it isn’t there then it is to use the super method.   Hope to have explained this a little better.       Regards Andrew Scott Analyst Programmer CMS Transport Systems Level 2/33 Bank Street South Melbourne, Victoria, 3205 Phone: 03 9699 7988  -  Fax: 03 9699 7976 Quote: I bet the human brain is a kludge. - Marvin Minsky ------------------------------------------------------------------------------------------------------ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Nando Sent: Friday, 25 November 2005 4:31 PM To: CFCDev@cfczone.org Subject: RE: [CFCDev] Facade - how to?   Andrew,   Something here i don't get. Why wouldn't a class be available? Did someone forget to write it? Does your application accept "outside requests" to create classes that may or may not exist?   You could use a try / catch block and if CreateObject() throws an error, catch it and create your default class. But if indeed that's along the lines of what you're after, something seems a little amiss in the architecture. There may be a more solid way to do what you need.   Maybe the exact detail would help flesh it out, rather than a theoretical explanation?        -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Andrew Scott Sent: Friday, November 25, 2005 4:16 AM To: CFCDev@cfczone.org Subject: [CFCDev] Facade - how to? I was hoping that someone might be able to help me out here; I am looking at creating a super class which can be extended by child objects, simple enough. But I also need to create a façade to interface to these objects.   Now I have been reading this list awhile now and not 100% sure on how to go about this. The façade needs to know what type of object to return, based on criteria for example this is what I am thinking.   Vehicle – Super   Car – Child   What I am interested to know, is how to I go looking for the required class and return a default class if the object I am looking for Is not there, so if I was looking for a bike and that class wasn’t available return say a default of the Vehicle class or something.   Anyway I have the concept just not the know how to go about it, so I little code examples would be good thanks.   Sorry if this has been asked a thousand times already.     Regards Andrew Scott Analyst Programmer CMS Transport Systems Level 2/33 Bank Street South Melbourne, Victoria, 3205 Phone: 03 9699 7988  -  Fax: 03 9699 7976 Quote: "Space...is big.
