Flash AS3: automate property assignment to new instance from arguments in constructor
- by matt lohkamp
I like finding out about tricky new ways to do things. Let's say you've got a class with a property that gets set to the value of an argument in the constructor, like so:
package{
public class SomeClass{
private var someProperty:*;
public function SomeClass(_someProperty:*):void{
someProperty = _someProperty;
}
}
}
That's not exactly a hassle. But imagine you've got... I don't know, five properties. Ten properties, maybe. Rather then writing out each individual assignment, line by line, isn't there a way to loop through the constructor's arguments and set the value of each corresponding property on the new instance accordingly? I don't think that the ...rest or arguments objects will work, since they only keep an enumerated list of the arguments, not the argument names - I'm thinking something like this would be better:
for(var propertyName:String in argsAsAssocArray){this[propertyName] = argsAsAssocArray[propertyName];}
... does something like this exist?
