[Arp] Arp and Zinc

[nyls]

Hey Michiel,

 

For me ARP is the base for my own framework/ platform where I work with, I
have added classes/ design patterns which help me build applications easier
and faster. ARP is very suitable for small applications but for the larger
applications there are need for extra classes. 

 

Also the Model Locator is now included in ARP and for me it is absolutely
necessary for building my apps because you have a single entry point to your
data and classes can listen for changes on the  model.  ( yes  the MVC
pattern rules )

 

What do you think ??

Patterns like this get a bit confusing to me sometimes.
Besides business delegates and a service locator, we now have service
delegates and a model locator. The uses of these last two are obvious, but
they are not part of the original arp implementation...
What scares me a bit is that arp might be forking in many directions, with
different people using different names for the same type of functionality,
inventing new patterns and implementing things in many different styles.

Do others have this feeling too? Maybe you can explain why, or even more
interesting, why not?

Thanks,
Michiel

Hey Colin,

 

There is an example from Grant which has a AuthenticationServiceDelegate
which uses fluorine remoting , he added a ServiceDelegate class which
handles 'gateway offline' 

http://theresidentalien.typepad.com/ginormous/2005/10/extending_arp.html

 

there is also the arp extension page http://www.osflash.org/arp_extensions
where there is a Shared Object Service maybe that's helpful also.. 

 

The cool thing about the servicelocator and serviceDelegates is that if you
switch your service the command can stay the same. The changes in the
external service (xml, remoting or sharedobject)  reflect the changes in the
serviceDelegate

 

In my words  ( and please list correct me if I am wrong)  a serviceDelegate
is used as a bridge between the server data-model and data-model needed in
the application.. So let's say first your app gets an array of objects
through a flash remoting service. The serviceDelegate gets them and returns
them to the command .. Now the remoting service is replaced with static XML
files. Your app still needs the array of objects, so in your 'new'
serviceDelegate you get the XML and reform them to an array of objects and
then pass them to the command. 

 

Ok hope this is of any help.

Hi Nyls,

 

I've been looking for an example which uses a ServiceDelegate, do you know
where I can find one.

 

Also I'm just trying to get this idea worked out in my mind, does this mean
I would have to write different commands for Zinc and remoting?

Hey,

 

I think best thing to place your Sinkcode is in a ServiceDelegate .. And
then add it to the ServiceLocator .. 

 

 

That way if in the future if  the Zinc part changes (maybe to flash
remoting, XML) you only have to switch your service ..

Hi,

 

I was hoping someone could give me some ARP advice regarding a flash desktop
application I'm working on which is using ARP and MDM zinc.

 

The App uses Zinc to get a directory list which in turn populates a Tree
component. What I'm trying to work out is the best place to put my zinc
code. Would it be best practise to create a command for example
getFileListCommand so all my calls from zinc are held in commands? if not
does anybody have a good way to do this as zinc's commands are synchronous.

 

Any help would be most appreciated.

 

Colin.
