One technique I've been trying lately is to assert linkage of class
names. First I create a static function that asserts that a symbol is
linked to a certain class. It returns the symbol ID if so, and throws an
error if not:
class com.exopolis.exosite.errors.SymbolError extends Error {
//...
public static function assertRegistered(linkageID:String,
classFunc:Function,
className:String):String {
if (!Object.registerClass(linkageID, classFunc)) {
throw new SymbolError(linkageID, className);
}
return linkageID;
}
}
Then in any MovieClip subclass, I can do something like this:
import com.exopolis.exosite.errors.SymbolError;
class mypackage.MyComponent extends MovieClip {
//...
public static var LINKAGE_ID:String
= SymbolError.assertRegistered("MyComponent",
MyComponent,
"MyComponent");
}
That way, the symbol is automatically registered to the class, and if
there is no such symbol, an error is thrown (which does not disrupt any
other processes).
