Yes, this one works fine but http://code.ericfeminella.com/downloads/Collections.zip is still 404

Thanks

Hmm, I believe the link resolves fine. Try it here: http://code.ericfeminella.com/classes/as3/LocalPersistenceMap.as.html

Hi Eric,
Thanks for this great API!
But it seems like Collections.zip archive isn’t available at http://code.ericfeminella.com/downloads/Collections.zip
Could you please fix or update the link?

Good point, initially I thought of this as well, however I opted not to perform the check as the IMap implementation is only intended to provide an interface into the data. The call to registerClassAlias is assumed by the client implementation as the internal check makes the implementation quite expensive to perform when it is not needed if the object is a value type.

With that being said I realized some people may want to perform the check internally therefore I did not define the LocalPersistenceMap as final so developers can extend to implement additional functionality such as this as needed.

Thanks,
Eric

Nice library.

I am wondering if you can store more complex information aswell. It would be nice for example if you would build in a check to see if complex objects have been registered before putting them in, something like this (from the top of my head):

function put(key:String, object:Object):void
{
var ba:ByteArray = new ByteArray();
ba.writeObject(object);
ba.position = 0;

var newObject:Object = ba.readObject();

if (describeType(object).@name != describeType(newObject).@name)
{
throw new Error (“If you save complex objects, make sure you use registerClassAlias to make sure they can be stored”);
};

};

It is just an idea
