Is there a way to see if a class exists? something like:

if( MyClass exist in the Library or has been imported in to the class ){  
var myClass = new MyClass()  
addChild(myClass);  
}else{  
trace(“MyClass doesn’t exist”)  
}

I’m not trying to see if it exists on the stage just want to know if I have access to it.
