AS3 Copy 对象

第一种：
public static function clone(object:Object):Object{
var ClassName:String = getQualifiedClassName(object);
复制代码

第二种：
package
{
import flash.utils.describeType;
import flash.utils.getDefinitionByName;
import flash.utils.getQualifiedClassName;

public class UtilFunctions
{


public static function newSibling(sourceObj:Object):* {
if(sourceObj) {

var objSibling:*;
try {
var classOfSourceObj:Class = getDefinitionByName(getQualifiedClassName(sourceObj)) as Class;
objSibling = new classOfSourceObj();
}

catch(e:Object) {}

return objSibling;
}
return null;
}

public static function clone(source:Object):Object {

var clone:Object;
if(source) {
clone = newSibling(source);

if(clone) {
copyData(source, clone);
}
}

return clone;
}

public static function copyData(source:Object, destination:Object):void {

//copies data from commonly named properties and getter/setter pairs
if((source) && (destination)) {

try {
var sourceInfo:XML = describeType(source);
var prop:XML;

for each(prop in sourceInfo.variable) {

if(destination.hasOwnProperty(prop.@name)) {
destination[prop.@name] = source[prop.@name];
}

}

for each(prop in sourceInfo.accessor) {
if(prop.@access == "readwrite") {
if(destination.hasOwnProperty(prop.@name)) {
destination[prop.@name] = source[prop.@name];
}

}
}
}
catch (err:Object) {
;
}
}
}
}
}
复制代码
第二种用法：
private var cloneObject:Object;
cloneObject = UtilFunctions.clone(source) as Object;//source是待克隆的对象
复制代码

都是在网上好不容易搜到的，不细解释代码了。
