Re: [flexcoders] Re: Help Me for SharedObject and registerClassAlias method
Use the metadata tag [RemoteClass(alias=WindowInfo)] above your WindowInfo
class declaration and your objects should be typed when you retrieve them
from SharedObject.

Hi,
i've yet posted this question but i can't resolve this problem..
i've created a custom value object class..a simple class with private
properties and getters methods to retrieve them.
public class WindowInfo
{
private var _id:String;
private var _module:String
private var _xpos:int;
private var _ypos:int;
private var _width:int;
private var _height:int;
public function WindowInfo(id:String, module:String, xpos:int,
ypos:int, width:int, height:int)
{
this._id = id;
this._module = module;
this._xpos = xpos;
this._ypos = ypos;
this._width = width;
this._height = height;
}
public function get id():String {
return _id;
}
public function get module():String {
return _module;
}
public function get xpos():int {
return _xpos;
}
public function get ypos():int {
return _ypos;
}
public function get width():int {
return _width;
}
public function get height():int {
return _height;
}
}
then i created an array collection where each item is an istance of
value object.
then i have a shared object manager that looks like this:
package util{
import flash.net.SharedObject;
import mx.collections.ArrayCollection;
public class SharedObjectApplicationManager {
private var mySO:SharedObject;
private var ac:ArrayCollection;
private var lsoType:String;
public function SharedObjectApplicationManager(s:String) {
init(s);
}
private function init(s:String):void {
mySO = SharedObject.getLocal(s);
if (getf()) {
getf();
}
}
public function getf():ArrayCollection {
return mySO.data.arrayc;
}
private function adda(array:ArrayCollection):void {
mySO.data.arrayc = new ArrayCollection();
mySO.data.arrayc = array;
mySO.flush();
}
}
}
so when i try to get arraycollection with getf method i get an
arraycollection of generic objects…not with windowinfo objects..in
this manner i can't get value properties of value object class.
so i would use registerClassAlias(Info, WindowInfo) where WindowInfo
is the VO..but where?
the architecture of my app is:
-main application (verify the shared object, if full then call a
public function of canvas to create windows with specific parameters
saved in windowinfo class)
–canvas (contains one or more windows)
any suggestions?
Thanks in advance

watch out for classes that take arguments in the constructer or java style
enums.

Re: [flexcoders] Re: Help Me for SharedObject and registerClassAlias method
I'm not sure what you mean about casting in this context. Also, I
guess you meant AMF3 when you said AMF2? (with AMF0/ AS2, you can use
Object.registerClass() for the same effect).
In AS3, registerClassAlias() is the way to make this work. But, as
Braam said, [RemoteClass] is the simplest way: it will insert the
registerClassAlias() code for you, so you don't have to worry about
where to put it, and will make sure it is ready when you need it.

What you're saying here works, but you can definitely use
RegisterClassAlias to get strongly typed objects when
storing/retrieving data from a SharedObject or anything else AMF2
based (LocalConnection for example). This would prevent the need to
cast any objects.
