Testing Thrown Error Handling

A quick way to test thrown errors are behaving as expected.

[Test]
public function testErrorHandling():void
        {
           

            var errorThrown:Boolean = false;
           
            try
            {
                callMethodThatCausesError();
            }
            catch (e:Error)
            {
                errorThrown = (e.message == 'SomeClass.ERROR_IN_DATA_MESSAGE');
            }
           
            assertTrue(errorThrown);

Channels endpoints and destinations, AIR and Flex, courtesy of weborb and midnightcoders

Endpoint - this is the URL where AIR/Flex app sends remoting/messaging requests to

Channel - a concept encapsulating the endpoint. Also identifies classes managing the channel on both client and server sides

Destination - identifies a server-side class exposed by WebORB. Used by Flex/AIR client to target method invocations against the referenced class.

Channels are configured in WEB-INF/flex/services-config.xml (and
weborb-services-config.xml if present in your system). Every channel has the "endpoint" element. For example, you have the following
channel definition:

<channel-definition id="my-amf"
class="mx.messaging.channels.AMFChannel">
<endpoint uri="weborb.php"
class="flex.messaging.endpoints.AMFEndpoint"/>
<properties>
<polling-enabled>false</polling-enabled>
</properties>
</channel-definition>

Notice the following line:

<endpoint uri="weborb.php"

"weborb.php" here is actually a URL. The reason it does not look like a URL is because it is relative. If your Flex app is loaded from

http://myhost/foo/AwesomeApp.html

then your application will be sending remoting requests to the following URL:

http://myhost/foo/weborb.php

(This is the reason why WebORB for PHP requires that you put weborb.php into the same directory containing your SWF.)

So how does the client know what channel to use. The answer lies in remoting-config.xml. This is where all the destinations are defined.
Most of the destinations do not explicitly reference the channels. For those, there's a special declaration at the top that establishes the default channel:

<default-channels>
<channel ref="my-amf"/>
</default-channels>

As a result, when you create a RemoteObject to talk to GenericDestination, remoting requests will be sent to the endpoint defined in the my-amf channel.

Now, suppose you need to get AIR to talk to WebORB. Obviously the my-amf channel will not work for you since the endpoint is relative.
You can definitely change the endpoint to be an absolute URL and it will solve the problem. Alternatively, take a look at the channel with
the following ID:

my-air-amf

Notice the endpoint URL for that channel is absolute. Now take a look at the GenericAIRDestination destination in remoting-config.xml. You will see it references the my-air-amf channel. As a result, if your
AIR application uses "GenericAIRDestination", your AIR client will talk to WebORB and send remoting requests to the endpoint URL from the
my-air-amf channel. It is important to adjust the URL to reflect the location of your WebORB instance.

Using Enterprise Architect to create a Class Model from an AS project.

1. Open EA the application.
2. From the app (if plugin in Eclipse select the Enterprise Architect option then ) Create a New Project.
3. Navigate to where you want your project to placed.
4. Your Project Browser perspective should be open and you'll see a tab called Model this is the project you've just created  a project is a collection models in EA. Select it.
5. Right Click on this and select 'Add a new model' using wizard.
6. Check the class model box. and Ok this, a class model icon will appear under the model icon in your project.
7. Right Click on the Class Model folder looking icon (not the blue one).
8. Mouse Over Code Engineering and select 'Import Source Directory'.
9. In the dialog box select ActionScript ensure file extension are .as and the options you prefer
10. Choose the Root Directory you want to generate a Class Model for.

11. To generate rtf documentation select the icon 4th from right on the toolbar with OR select F8 it looks like lines with ticks and crosses although there are two of them.

Registering a remoteclass alias dynamically

Say you've got a value object (VO) and you have defined a remote class alias on it. You can change(add?) another alias dynamically at runtime.
When you perform the execution of a service call.

eg [RemoteClass(alias="lf.Project.Service.ServiceProxy.ObjectivesServiceProxy.StoreCluster")] on the class

com.fasanya.application.vo.StoreClusterVO.

To change this at runtime particularly useful if the same VO is used by different services you can do this...

public function execute(event:CairngormEvent):void  //often done in this method of a command
{

   var clientClassName:String = 'com.fasanya.application.vo.StoreClusterVO';

   var clientClass:Class = getDefinitionByName(clientClassName) as Class;

   var newAlias:String = ''lf.Project.NewService.NewServiceProxy.NewServiceProxyName.StoreCluster";

   registerClassAlias(newAlias, clientClass);

  ...other code...

  delegate.serviceRequest(clientClass);
}

Emergent Design - These few simple rules, applied locally, can help a high quality global design to emerge.

In a posting on the Agile Modeling mailing list, Alan Shalloway of Net Objectives, proposed some rules on well designed code:

1. Runs all the tests
2. Follows once and only once rule
   (which I believe means “contains no duplicate code”)
3. Has high cohesion (clarity)
4. Has loose coupling

Alan comments:

“If you look at design patterns, you can see that most of them follow these rules. High cohesion and loose coupling can often be achieved by decomposing your problem domain with the distinctions of commonality / variability analysis. That is, find how things are similar and then find out how they are different.

“The other thing I like about this set of rules is that they are easy to teach and understand. Cohesion has to do with clarity. Method cohesion means a method is focused on one purpose. Class cohesion means all of the methods in a class are focused on one larger purpose.”
