apache-flex - ActionScript-3 : Array vs. ArrayList

Question

谁能告诉我哪个更快:Array 或 ArrayList？ (ActionScript3)

我试图找到关于此的页面，但没有找到任何内容。谢谢。

Answer 1

The ArrayList class is a simple implementation of IList that uses a backing Array as the source of the data. Items in the backing Array can be accessed and manipulated using the methods and properties of the IList interface. Operations on an ArrayList instance modify the data source; for example, if you use the removeItemAt() method on an ArrayList, you remove the item from the underlying Array.

显然 ArrayList 类包装了一个 Array 对象——因此一个普通的 Array 会比一个 ArrayList 对象更快。
