Does Object Exist?

Purpose

To check if an object class exists in your application / library path

How To Use

I would suggest creating the following code as a non-visual class function, preferably as part of the application controller in a framework. It may equally be used anywhere, including as a global function. The function requires a single parameter, and a return type of boolean.

Code

Function

of_DoesObjectExist( readonly string as_classname ) returns boolean

Suggestions

Useful when you're creating applications which rely upon dynamic object creation, can be used to prevent crashes by checking that the object class exists before creating an object or opening a window. Can also be used in debugging to check that you've included any dynamically created objects in your application.
