hello,
I'm triyng to code a M2T which has a model+profile UML as input and generate java classes as output, in Acceleo.
I have a problem to manipulate a DataType.
In my profile, i have :
*a stereotype "stereotype" with 2 attributes:
- attr1:type DataType "DT",
- attr2:type Enumeration "enum"

*DataType "DT" with 2 Properties:
-L1: Boolean
- L2 : string

*Enumeration "Enum" with 2 literals

*In my model, I have 2 classes (class1, class2)
*class2 has a Property "P1" :
- type Class1,
- Profile: "Stereotype" is applied: attr1 (L1 : True, L2:"abc"). attr2 (literal1).

here is my generate.mtl file,
[template public generateClasses(aClass : Class) ]
[comment @main/]
[file (aClass.name.concat('.java'), false, 'UTF-8')]

public class [aClass.name/] {
[for (p: Property | aClass.attribute) separator('\n')]
	[for (sp : Stereotype | p.getAppliedStereotypes())]

private p1=[p.getValue(str,"enum").oclAsType((EnumerationLiteral).name/];
private p2 =[p.getValue(str,"DT").oclAsType(([color=red]DataType[/color]).name/];
      [/for]
[/for]
}
[/file]
[/template]

In the generated class.java, I can extract the value of the enumeration literal of my model, but not the DataType.
I need to get the value of DT-->L1.

Can Someone help me please ?
thx

Hi

No. You cannot expect us to debug your 100/1000 line problem when you only give us 4 lines to look at.

I have juste modified my first message. I hope it's clearer than the 1st request.

Hi

Please do not modify your messages other than to correct trivial typos; it potentially makes the thread unreadable by anyone else.

No clearer. What you provide is certainly not your MTL file. Why is there a [color=red]? You have not provided any of your models; just hints at how you intended them to be created. Perhaps https://wiki.eclipse.org/OCL/ForumNetiquette may help you understand how to communicate more profitably.

Hi,
I apologize for my quick reply.
I'll try to make more effort to be clearer as possible. I attached to my reply my model (screenshot + zipped file) as I created it in Papyrus, showed the applied stereotype with its properties as I explained in my first request.
The code I wrote is a real MTL code file, I intentionally added color=red in the first request to highlight the problem (which is data type), before I changed the [code format.

[comment encoding = UTF-8 /]
[module generate('http://www.eclipse.org/uml2/5.0.0/UML')]

[template public generate(aClass : Class)]
[comment @main/]
[file (aClass.name.concat('.java'), false, 'UTF-8')]

public class [aClass.name/] {

[for (p: Property | aClass.attribute) separator('\n')]
	[for (sp : Stereotype | p.getAppliedStereotypes())]
//instance stereotype - type-  name :
@[sp.name/] [p.type.name/] [p.name/];

private p1=[p.getValue(sp,'enum').oclAsType(EnumerationLiteral).name/];
private p2 =[p.getValue(sp,'DT').oclAsType(DataType).name/];
      [/for]
[/for]
}
[/file]
[/template]


This is the code java generated for one class:
public class Class2{
	//instance stereotype - type-  name :
	@stereotype Class1 Property1;
	private p1 = e1;
	private p2 = invalid;
	
	//instance stereotype - type-  name :
	@stereotype Class1 Property2;
	private p1 = e2;
	private p2 = invalid;
	
	}


I would like to generate in java something like that ( instead of "invalid") :
private p2 = {{L1 :true}, {L2: "abc"}} ;


i don't know how to get The DT attributes and their values ( L1 and L2 values in the model)
Any help for this problem please?

Hi

Your ZIP is missing at least models and transformations.

Hello,
Here is a zipped file with a complete project "genMyModel":
- "models" folder contains "expmodel" and "MYprofile" : uml profile applied to the model. + graphical diagrams
- "src" folder : generate.mtl (transformation rules)
- "destinationCode": contains the generated java classes

My questions are :
1- how to generate "private p2 : L1" (DataType) as mentioned in my first msg
2- how to generate Ports and Connectors (ClientEnd, SupplierEnd) considering their stereotype properties.
eg: "ConnectorStereotype" applied on "Connector" in the Expmodel.

best regards

Hi

A little bit of traditional 'printf' debugging works well for M2T.

[if (sp.name.equalsIgnoreCase('stereotype1') )]
/* [p.getValue(sp,'Attribute2')/] */
/* [p.getValue(sp,'Attribute2').eClass()/] */
/* [p.getValue(sp,'Attribute2').oclAsType(EnumerationLiteral)/] */
/* [p.getValue(sp,'Attribute2').oclAsType(EnumerationLiteral).name/] */
private p1=[p.getValue(sp,'Attribute2').oclAsType(EnumerationLiteral).name/];
/* [p.getValue(sp,'Attribute1')/] */
/* [p.getValue(sp,'Attribute1').eClass()/] */
/* [p.getValue(sp,'Attribute1').oclAsType(DataType)/] */
/* [p.getValue(sp,'Attribute1').oclAsType(EClass).name/] */
private p2 =[p.getValue(sp,'Attribute1').eClass().name/];
[/if]

reveals that

/* org.eclipse.uml2.uml.internal.impl.EnumerationLiteralImpl@655ef322 (name: e1, visibility: <unset>) */
/* org.eclipse.emf.ecore.impl.EClassImpl@550ee7e5 (name: EnumerationLiteral) (instanceClassName: null) (abstract: false, interface: false) */
/* org.eclipse.uml2.uml.internal.impl.EnumerationLiteralImpl@655ef322 (name: e1, visibility: <unset>) */
/* e1 */
private p1=e1;
/* org.eclipse.emf.ecore.impl.DynamicEObjectImpl@58fb7731 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@3a6f2de3 (name: DT) (instanceClassName: null) (abstract: false, interface: false)) */
/* org.eclipse.emf.ecore.impl.EClassImpl@3a6f2de3 (name: DT) (instanceClassName: null) (abstract: false, interface: false) */
/* invalid */
/* invalid */
private p2 =DT;

Attribute1 is a DT not a DataType. DT is a profile type that doesn't seem to be known to Acceleo; presumably needs a cleverer import. Perhaps Acceleo can only cope if the profile is statically generated.

Anyway using eClass() works fine.

Thank you for your answer. I'm trying to change my code using EClass.
I'll post my solution if it works, may be it can help others!

However, my 2nd question was about connector generation with mtl. I have no idea how to do it. I used a stereotype "ConnectorStereotype" applied on a connector between 2 properties (as it's described in my model). I need to generate :
- connector Ends ( ClientEnd, SupplierEnd)
- "repetitive" value : a propertie of "connector stereotype".

Any example or help for that, please ?
best regards,
sana

Hi

I don't understand the problem. It seems that you have some information in the model that you want to render. So you do a bit of navigation, querying, formatting.

You need to at least demonstrate what you are failing to do to get any help on why you are failing. And of course learn to use a debugger. That's how I learned and continue to learn.
