Coldfusion check if function exists

Question

Hello is there a way to check if a function exists in coldfusion. It is throwing an error function is not defined

Answer 1

I believe isDefined('functionname') works. So you can do:

<cfif isDefined('functionname')>
    <cfset functionname() />
</cfif>

If it's a potential method of an object named obj for example you can also do:

<cfif structKeyExists(obj,'functionname')>
  <cfset obj.functionname() />
</cfif>

Or

<cfif isDefined('obj.functionname')>
  <cfset obj.functionname() />
</cfif>
