What's the best way to reuse functions in a Flex MVC framework?

I am using MVC Cairngorm architecture for my current project.

I have several commands that use the same type of function that returns a value. I would like to have this function in one place and reuse it, not duplicate code in every command. What's the best way to do this?

Create a static class or static method in one of the Cairngorm classes.

class MyStatic
{
    public static function myFunction(value:String):String
    {
        return "Returning " + value;
    }
}

Then where do you want to use your function:



import MyStatic;

var str:String = MyStatic.myFunction("test");

Another option is to create a top-level function (a la "trace"). Check this post, I wrote here .

You have many options here - publicly defined functions in your model or controller, for example:

var mySharedFunction:Function = function():void
{
   trace("foo");
}


... static methods for new or existing classes, etc. The best practice probably depends on what the function is supposed to do. Can you clarify?

Create an abstract base class for your commands and add your function to the protected area. If you need to reuse it elsewhere, reformat it into a public static method in the utility class.
