Nick, Cold fusion doesn't use constructors in a traditional sense, but the concept still applies to the invocation. You are instantiating a component or object and you will use it's methods and properties when it's instantiated. You can even make the object persistent using application and/or session scopes (There's a great article on persistence on desdev or CFDJ - I think it was Ben who wrote it). To put it another way, when you invoke a web service the platform you are on uses the WSDL file. The file describes the class, it's properties, methods and interfaces.
The platform is able to use the WSDL information to create a "stub" or a "proxy class" that acts (to the code) as if the class is local. In other words it acts as any other class - or component - acts for that platform. It's basically the same concept as an RPC call - without the proprietary baggage (theoretically <g>). In fact, that is the way web services are often described: "the ability to make an "RPC-like" calls across platforms over standard protocols (XML and http)". So if a platform uses constructors, a constructor for the class looks similar to any other constructor. The internals are "masked" from the code by the proxy - giving you the buzzword pillars of OO (again... theoretically) "encapsulation and abstraction". Again, the process is applied differently on different platforms. -mk -----Original Message----- From: Nick McClure [mailto:cf-lists@;king-nacho.com] Sent: Friday, October 25, 2002 9:50 AM To: CF-Talk Subject: RE: CFC in .NET How does one deal with things like Constructors and such? > -----Original Message----- > From: Ben Forta [mailto:ben@;forta.com] > Sent: Friday, October 25, 2002 10:07 AM > To: CF-Talk > Subject: RE: CFC in .NET > > And you could also write a CFC in CF and invoke it from within .NET. > > --- Ben > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Structure your ColdFusion code with Fusebox.
