Dear all,

I got a meta-model like the picture that I've attached

I want to get the "value" from that meta-model with this code
[for (it : Feature | aFeatureModel.eAllContents(Feature))]
	[if (it.attributes->notEmpty())]
		[i/]. [it.name/] with attributes [it.attributes.name/] and value [it.attributes/]
 		[else]
		[i/]. [it.name/]		
	[/if]	
[/for]


I hope the output will be like this
1. [Feature_name] with attributes [name of feature's attribute] and value [value of attribute]

but instead of that result, I got
1. [Feature_name] with attributes [name of feature's attribute] and value
org.hyperflex.featuremodels.impl.SimpleAttributeImpl@6e486976 (name: amount) (type: Int, value: in [0..5])


I think my problem is I can not get the contained items in second round bracket (type: Int, value: in [0..5]). So, I change the code to
[it.attributes.value/]
but I got an error message "Unrecognized variable: (value)"

I hope someone can help me solve this problem Surprised

Thank you

Regards,
Irfan

attributes is a Collection so you should probably iterate over it, but
if really want just one attributes->any(true).value should work.

Hello Ed,

thank you for your reply. Yes it's true that attributes is a collection.
I've tried your code but I still get the error message "Unrecognized variable: (value)"

I think I cannot do direct access to value since it's in the second round bracket in this result (I make it red) -> org.hyperflex.featuremodels.impl.SimpleAttributeImpl@6e486976 (name: amount) (type: Int, value: in [0..5])

I can do a direct access like attributes->any(true).name and I get "amount" as a result since it's in first round bracket.

Regards,
Irfan

Hi

I've completely lost you. You might find
https://wiki.eclipse.org/OCL/ForumNetiquette provides some ideas on more
effective communication.

I am sorry if I made you a little bit confused.

I just want to get the value of my model's attribute. I have provided the meta-model and I think I can get that value just by using this code
[it.attributes.value/]


I have put your code and I get an error message like in the picture I've attached in this reply

Hope it helps you see my problem

Thank you

Regards,
Irfan

Hello

I use Eclipse Modeling Tools Kepler v.4.3 and Acceleo v.3.4

I have attached my project and I am not so sure if I should provide the meta-model too if I've provided my project.

Thank you very much

Regards,
Irfan

Hi

I'm not sure how you think I can look at your project when you omit half
of it.

Two email exchanges ago I referred you to "You might find
https://wiki.eclipse.org/OCL/ForumNetiquette provides some ideas on more
effective communication. "

Yet you still ask me to waste my time looking at a problem that you
won't show me. This of course is a waste of your time too. And everyone
else's since you have just prevented me working on something more useful.

Regards

Ed Willink

So, I do not know if I throw a half of my project.

I am really sorry for my mistake hope you still can help me,sir

Thank you

Hello,

Okay, I am trying to make a better explanation. So, I hope everyone can see a better perspective.

In my project, there is a folder called "model".
This folder contains my feature diagram named "account.featuremodel_diagram" and the model of that feature diagram called "account.featuremodel"
I made that diagram using HyperFlex Feature Diagram editor that I found in its update site http://lucagherardi.it/projects/HyperFlex/UpdateSite
So, if you do not mind please install new software in eclipse using that link first.
and if no plugins are showed try to unflagged "Groups item by category" like this picture

http://i57.tinypic.com/28cledx.jpg

The meta-model is included in that tools.
I have no idea how to extract just the meta-model from that tools,
that's why I did not provide the meta model.
And the for the launch configuration I made it this way

http://i59.tinypic.com/nlpq86.png

My problem is I want to get the value in feature diagram that I've made.
I do not know how to get that value like my first post.


Thank you

Best regards,
Irfan

Hi

If you want help you should expect to make the job easy, not give a list
of special non-Eclipse installs.

If you cannot provide a sensible repro, I am sorry, but you will have to
hope that someone else on this newsgroup can help.

Regards

Ed Willink
