I also omitted the code showing how the singletons were created and called (now added). So here's the new improved code!

For those who don't know sigletons are a class that can only have one instance. They can be thought of as a glorified global variable - but are a lot more useful. Most ColdFusion classes, or rather instances of CF components, can be turned in a singleton by placing the following code in your Application.cfm: <code> <cfif not structkeyexists(application,<instance name>)> <cfset application.<instance name> = createobject("component",<path to component>)> </cfif> </code> or OnApplicationStart method of your Application.cfc: <code> <cfset application.<instance name> = createobject("component",<path to component>)> </code> [More] ColdFusion Design Patterns Singleton Mon, 09 Apr 2007 23:30:00 +1000 http://blog.classsoftware.com/index.cfm/2007/4/9/ColdFusion-Singletons
