How to create a method that can accept arraylist/collection of object - custom class type in actionscript

Question

Like java, I want to create a method that accepts an array list of particular object type.

In java:

public void addStudents(List<Student> students) {
...
}

In actionscript

public function addStudents(students:ArrayCollection):void {
.....
}

Here I want to have public function addStudents(students:ArrayCollection).

Thanks

Uh, and where is the problem? Is something wrong with mx.collections.ArrayCollection? — Martin

If I do this, some one can pass some other object array as well. — priyank

it will fail later on but I want to stop them and ask explicitly to pass an array of student type objects. — priyank

If you have a Student object and publish for FP10 you can use the Vector object.

public function addStudents(students:Vector.<Student>):void {}

As far as i know, AS has no template-like generics. But you can extend ArrayCollection into something like StudentArrayCollection with more rigid type check inside.
