how to use one object pool for multiple objects - actionscript-3

Question

This is an example of one I found online and used (I'm new to object pooling). It works for a single object type but won't allow me to create a pool of different objects
package
{
import starling.display.DisplayObject;
public class SpritePool
{
private var pool:Array;
private var counter:int;
public function SpritePool(type:Class, len:int)
{
pool = new Array();
counter = len;
var i:int = len;
while(--i > -1)
pool[i] = new type();
}
public function getSprite():DisplayObject
{
if(counter > 0)
return pool[--counter];
else
throw new Error("You exhausted the pool!");
}
public function returnSprite(s:DisplayObject):void
{
pool[counter++] = s;
}
}
}

Here is an example of object pool without object count limit.
import flash.utils.Dictionary;
import flash.utils.getDefinitionByName;
import flash.utils.getQualifiedClassName;
public class ObjectPool {
public function ObjectPool()
{
throw new Error("don't create instance");
}
private static const objectDict:Dictionary = new Dictionary();
public static function getObject(c:Class):Object{
//if you want add a object count limit,try to check the count here
if (objectDict[c] == null) {
objectDict[c] = [];
}
var t:Array = objectDict[c] as Array;
if (t.length > 0) {
return t.shift();
} else {
return new c();
}
}
public static function putObject(obj:Object):void {
var c:Class = Class(getDefinitionByName(getQualifiedClassName(obj)));
if (objectDict[c] == null) {
return;
}
var t:Array = objectDict[c] as Array;
if (t && t.indexOf(obj) == -1) {
t.push(obj);
}
}
}
