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,
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
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.
