剪切复制粘贴用的DisplayObject（集团UIComponent）的动作脚本3柔性4 [英] cut copy paste with DisplayObject(Group ,UIComponent) in action script 3 flex 4

问题描述

我在执行剪切复制粘贴在我的应用程序，如 cacoo 。但我这些操作过程中遇到的问题。 我使用的背后剪切复制粘贴的想法

I am implementing Cut Copy Paste in my application like cacoo. but I face problem during these operation. i'm using idea behind cut copy paste

var className:String = getQualifiedClassName(objcut.getItemAt(i))
var klass:Class = getDefinitionByName(className) as Class
var cloneObject:* = new klass()

所以我不能够preserve对象的所有属性。 还有就是执行柔性4.how这些操作我可以复制的Flex 4（AS3）的图形对象中的任何其他的想法。复制对象并粘贴多次。

so i'm not able to preserve all property of object. There is any other idea to perform these operation in flex 4.how can i copy an Graphical object in Flex 4(as3). Copy an Object and paste multiple times.

推荐答案

以与性能对象的副本，最简单的方法是使用的ByteArray：

The simplest way to make a copy of object with properties is using ByteArray:

public static function copy(value:Object):Object
{
    if (!value)
        return null;

    //register object class to prevent Error #1034: Type Coercion failed
    registerClassAlias(getQualifiedClassName(value), value.constructor);

    var buffer:ByteArray = new ByteArray();
    buffer.writeObject(value);
    buffer.position = 0;
    var result:Object = buffer.readObject();
    return result;
}

但你仍然可以得到错误＃1034嵌套类。您需要注册别名所有嵌套类prevent此之前，一些启动方法制作副本，例如。

But you can still get the error #1034 for nested classes. You need register aliases for all nested classes to prevent this before making copy, for example in some startup method.
