[flexcoders]Count the number of arguments on a function

[dorkie dork from dorktown]

Is there a way to count how many arguments there are on a function from
outside that function? For example,

Class1:
// myFunction has one parameter of type string
myFunction(myParam:String) {

}

Class2:
someFunction() {
    // for example,
    // i want to get a count of arguments of myFunction, name, if they are
required and their type
    var argumentLength = class1.myFunction.arguments.length;
    var argumentName = class1.myFunction.arguments[0].name;
    var argumentClass = class1.myFunction.arguments[0].class;
    var argumentRequired = class1.myFunction.arguments[0].required;
}
