AS3：如何将向量转换为数组 [英] AS3: How to convert a Vector to an Array

问题描述

什么是一个矢量转换为ActionScript3的阵列？

What's the nicest way to convert a Vector to an Array in Actionscript3?

通常的铸造语法不工作：

The normal casting syntax doesn't work:

var myVector:Vector.<Foo> = new Vector();
var myArray:Array = Array(myVector); // calls the top-level function Array()

由于Array函数的存在性。在阵列中的上述结果，但它是用由原始向量的一个元素的阵列

due to the existance of the Array function. The above results in an array, but it's an array with a single element consisting of the original Vector.

这叶稍微更复杂的：

var myArray:Array = new Array();
for each (var elem:Foo in myVector) {
    myArray.push(elem);
}

这是很好的，我想，虽然有点罗嗦。这是规范的方式做到这一点，还是有一个的toArray（）函数中的标准库藏在什么地方？

which is fine, I guess, though a bit wordy. Is this the canonical way to do it, or is there a toArray() function hiding somewhere in the standard library?

推荐答案

你的方法是最快的。如果你认为这是为详细，然后建立一个效用函数...：）

your approach is the fastest ... if you think it's to verbose, then build a utility function ... :)

编辑：

要建立一个实用的功能，你可能会删除该类型如下：

To build a utility function, you will probably have to drop the type as follows:

function toArray(iterable:*):Array {
     var ret:Array = [];
     for each (var elem:Foo in iterable) ret.push(elem);
     return ret;
}
