I too am interested in a native port and was about to dig into the source in the svn link you provided in another post (http://svn.puremvc.org/PureMVC_JS/branches/native-multicore/).  Mainly documentation left?  FWIW, I would be happy to help however I can in that area while I am digging.

After a lot more reading last night I realize this wasn't really a feasible question.  AMF isn't just a format, it's also how the messages are sent and received.  Technically, I could implement the serialization in the viewcomponent, but I would also have to address the RPC portion as well (like SOAP or REST).

I'm writing a basic API to some backend settings and I would like to return the results in different formats (xml, html, etc) for different frontends to consume.  How would I go about outputting amf?

I can think of three different routes (and none seem like they would be feasible)..

Wrap the facade within the services class...and somehow return data from the viewcomponents?

Create the gateway/services and pass that into the API to be used as a viewcomponent...and somehow still be able to access it properly as a remote object?

Something like this: http://efreedom.com/Question/1-1942890/Self-Contained-Library-Serializing-PHP-Data-AMF where I basically have to format the amf output myself.


Any ideas greatly appreciated!

I'm confused. You are setting XML, type regular string, as Proxy data? Why not set DOMDocument instance or SimpleXMLElement instance as Proxy data?

No, I am wanting to use the DOMDocument or SimpleXMLElement instance as the proxy data.  My question was more related to how to implement either of them.  For example, if I have this...

:

<?php
class FooBarProxy extends Proxy implements IProxy
{
    public function loadXML($filename)
    {
        $xml = simplexml_load_file($filename);
        $this->setData($xml);
    }

    public function getNodeValue($nodeName)
    {
        return $this->getData()->$nodeName;
    }
    
    public function setNodeValue($nodeName, $value)
    {
        $xml = $this->getData();
        $xml->$nodeName = $value;

        $this->setData($xml);
    }
}
Whenever I call setNodeValue, I am basically creating a second copy of the xml data in order to update with the new value.  In AS3, getData returns a reference to the actual data so in terms of PHP it would something like this...

:

public function setNodeValue($nodeName, $value)
    {
        $this->getData()->$nodeName = $value;
    }


My overall question is..would my original setNodeValue function from the first code snippet be considered "correct"?  Ie.  make a local copy of the xml instance, manipulate it, then setData. 
To me, making that second local copy just seems inefficient.  I would think it would be better to use the proxy to somehow manipulate the data directly...not make copies, manipulate, then setData.

I have several proxies that interact with their own corresponding xml file.  The xml is then used as the proxy data to manipulate.  I am stumped as to how to change the xml data....or better yet, I am stumped because "getData()" does not return a reference (like AS3 does).  It seems in my setter functions, I would have to pull the entire contents of the xml in to a variable, do the necessary changes, then "setData()" with the updated xml data.  OR, I override the getData() to return a reference.  OR, I use a delegate to do the xml manipulation and use the delegate as the proxy data.  No matter which way I try to implement it, I get the feeling I'm doing it wrong.  Any advice or suggestions?

Thanks

I noticed that the puremvc php files contain the closing tags.  Personally I leave them out of files that are pure php to avoid possible 'headers already sent' errors.  What are the maintainers thoughts on this?
