You can do pretty much the same thing in CF.
private any function callMethod (required string functionName, fnArgs) {
var thisFn = variables[arguments.functionName];
if (structKeyExists(arguments,'fnArgs')) return
thisFn(argumentCollection=arguments.fnArgs);
else return thisFn();
}
This is a method I wrote a while back to work with onMissingMethod. (caveat
- I wrote it, but I may have "stolen" knowledge from other places)
Obviously this is a pure CF9 script function, but you can put it into an
ordinary CF8 function and it will work.
It needs to be applied to the object you're working with, so you'd add this
to your decorator (or a base decorator that you extend off of, so you aren't
repeating code all over the shop)
Then, using your example above, you'd call it like this
object.callMethod(propertyname)
Thats about it really.
Obviously its not built in, but not hard to implement and doesn't use
evaluate().....
