CFCs don't have true constructors at this time. To make up for that, several people have standardized around the idea of a method called init(), but it's up to the programmer to call init(); the system doesn't do it itself.

Java for ColdFusion Programmers Fusebox 4 Mach-II OO Applications with CFCs -----Original Message----- From: Ian Skinner [mailto:[EMAIL PROTECTED] Sent: Thursday, September 04, 2003 2:58 PM To: CF-Talk Subject: RE: CFC/Object Best Practice That is indeed what I was trying to figure out. Got almost there myself. I'm wondering about your constructor? <!--- "constructor" ---> <cffunction name="init"> <cfset variables.engine = createobject("component", "Engine")> </cffunction> I was under the impression that CFC did not have a true "constructor", but rather a psudo-constructor in that code between the <cfcomponent> tag and the first <cffunction> tab would be run once when the component is used. Is this correct, or is there something special about a function named "init"? -------------- Ian Skinner Web Programmer BloodSource Sacramento, CA -----Original Message----- From: Tim Blair [mailto:[EMAIL PROTECTED] Sent: Thursday, September 04, 2003 9:44 AM To: CF-Talk Subject: RE: CFC/Object Best Practice > And how would this look in the code of a CFC? I'm guessing what you mean is something like this: <cfcomponent name="Car"> <!--- "constructor" ---> <cffunction name="init"> <cfset variables.engine = createobject("component", "Engine")> </cffunction> <!--- a function which calls something from the engine ---> <cffunction name="checkOil"> <cfreturn variables.engine.getOilLevel()> </cffunction> </cfcomponent> ?
