[Flashcoders] AIR Socket.readObject received in multiple ProgressEvents?
In a the client of a client/server AIR app I have:
function onSocketData(event:ProgressEvent) : void {
var result = _socket.readObject();
// do something with result
}
How can I be sure the whole object is available before I try to use it?
Things work as expected most of the time, but with large pieces of data or on
laptops will hang when operating over a wireless connection, so I suspect the
object is spread out over multiple ProgressEvents.
I can only find pseudo code illustrating what you should do reassemble an AMF
object received in separate ProgressEvents.

Re: [Flashcoders] AIR Socket.readObject received in multiple ProgressEvents?
Hi,
Are you sure that this is not something server-side?
I have had similar problems which were compounded when using Wireless
connections - we traced the fault back to the server code giving up
filling the socket buffer when it got a buffer full event?
Apart from that you could use some sort of paradigm like:

Re: [Flashcoders] AIR Socket.readObject received in multiple ProgressEvents?
Basic TCP rules says that you are sending an octet stream. All socket APIs are optimized for bulk access to avoid silly performance issues due to lots of function calls (and possible mode switches). This means that you MAY get more than one object in one go and that you MAY get only a part of the object(s) at the ends of the buffer. You need to separate data manually. You have three strategies: * Fixed size (easy, not flexible) * Terminator (slightly tricky with buffers, flexible, possible escaping issues, slight overhead) * Transmitted size (easy with buffers, flexible, slight overhead) ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] AIR Socket.readObject received in multiple ProgressEvents?
I've not considered it may be a server issue. The server is also an AIR app - looking at the documentation there doesn't seem to be any events related to sending data over sockets - is it possible to tell if data was successfully written to the socket?

Re: [Flashcoders] AIR Socket.readObject received in multiple ProgressEvents?
I've been unsuccessful at finding an example of a functional AS app which uses
one of the second two approaches, I can only find broad descriptions of what
needs to happen.
It appears that Socket.bytesAvailable functions differently depending on the
version of AIR, either representing the number of bytes which haven't yet been
read or the cumulative total of bytes sent over the socket.
If I have to do this without looking at functional examples, how would one
transmit a terminator byte or byte size while using Socket.writeObject()?
Perhaps the reason I can't find examples is it's not even a good idea to try?
The problem I'm trying to solve is to transmit an instance of a class like this
from the server app and reassemble it on the client:
package mn.webershandwick.firebell.data {
import fl.data.DataProvider;
public class SiteVO extends Object {
public var siteId:String;
public var posts:Array;
public var profilesDataProvider:DataProvider;
public function SiteVO() {}
}
}
Socket.writeObject and Socket.readObject does everything for me but fails
consistently when the amount of data held in the variables is large and
intermittently at any size over a wireless connection.

You can't know in the general case, but here is a good enough guess:
function isFirstMovie():Boolean {
return stage root==stage.getChildAt(1);
}
There is however one specific case where you can know: During the
construction of the first frame (that includes the document class
constructor). Check if you are on the stage during that. Only the first
loaded movie will be, any subsequently loaded movies will not be.

Re: [Flashcoders] MVC style
I am an MVC purist, I always proceed as follows: Models should ONLY store information, particularly the state of the application and any data retrieved from disk or the network. Views hold a reference to a model, watch it for updates, and respond to those updates by rendering the model in its current state. 'rendering' could refer to manipulating the display list in flash, outputting some text to stout (or trace) serving up some JSON from a server app, whatever way of expressing the state of the model your app requires. Views are also responsible for handling events that occur in their domain, and forwarding them to the appropriate Controllers. Controllers exist to manipulate models. The only acceptable way to alter a model is via a controller. Whether its storing data from a Web service in the model, or altering the state of the app in response to user interaction, the controllers hold all of the business logic that define how the app behaves. Ideally, in AS3, the models consist of no methods except accessors that retrieve values from private vars and store values there and notify subscribed views of the update. Event dispatcher is a fantastic base class for a model. Equally, wherever possible, a controller should only consist of methods. Properties are for the model. This sets up a unidirectional flow of interaction and display. The controller populates the model, the model notifies the views, the views change. The changed view incites some user interaction, the view tells the controller what the user wants to happen, and the controller alters the state of the model accordingly, which then notifies the views to change, and so on and so forth.
