I want to create a class that will mainly house a Vector. The class will have some methods that deal with items in the Vector.

The issue I am having at the moment is that I can’t work out how to dynamically create an instance of Vector. So far I’ve tried this and similar with no luck:

public class List
{
    private var _content:Vector;

    public function List(type:Class)
    {
        _content = new Vector.<type>();
    }
}

    This post by Paul Robertson (previously Senior ActionScript Developer/Writer at Adobe) provides a little more information on how Vectors are declared:

    The Vector class allows (requires) you to specify the type it will
    contain at compile time — both for variable declarations and when
    creating instances.

    Because the type parameter is a literal, it must be provided at compile time. In fact, every reference to a Vector is checked at compile time, with the exception of .shift() and .unshift, which are checked at run time.

    Adobe’s article on indexed arrays provides some more interesting information on that. In fact, it mentions that strict compile time type safety is one of the key features of Vectors.

    In short: It is not possible to use a variable to set a Vector’s type, because the type parameter is a literal and a compile time requirement.

    Hope that helps!
