[ACCELEO] Generate Declarations [message #1681833]

Hi,

I want to generate simple declarations with Acceleo in one of these two ways:

1.
[for (property :Property | c.eContents(Property))]
[PropertyDeclarations(property)/]
[/for]

[template public PropertyDeclarations(property:Property)]
[property.type.getStereotypeValue('Ecore::EDataType', 'instanceClassName')/] [property.name/] = [property.defaultValue/];
[/template]

2.
[c.attribute.type.getStereotypeValue('Ecore::EDataType', 'instanceClassName')/][c.attribute.name/];

Output
1. Yields this as the output
double in = ;
double out = ;
double v0_ = org.eclipse.uml2.uml.internal.impl.LiteralRealImpl@7b87d668 (name: <unset>, visibility: <unset>) (value: 0.0);
double v1_ = org.eclipse.uml2.uml.internal.impl.LiteralRealImpl@d18c0be (name: <unset>, visibility: <unset>) (value: 1.0);

So here I only want to consider the properties which are not ports: meaning 'in' and 'out'
And I want to access the values 0.0 and 1.0 respectively, but it does not work with [property.defaultValue.value/].....

2. If I try it another way with the code in 2. I get the following:
doubledoubledoubledouble inoutv0_v1_;

So basically I am wanting to know how I can change the code to get just the Parameters without the ports (I used the Parameter Property under Contraints and Comments) and in the right order, like this:

double v0_;
double v1_;

Thank you,
Frank

Dear Frank,
If you want to filter those who are not ports usually in the "for"
clause you should use some OCL. Something like:

[for (property :Property | c.ownedElement->select(p |
p.oclIsKindOf(Property) and not p.oclIsKindOf(Port)))]
[PropertyDeclarations(property)/]
[/for]

For the Real literal to be shown, please, try using explicitly
".toString()" for defaultValue.

Best,

Víctor

Thanks Viktor,

the loop works perfectly fine.
It just gives the warning 'Possible incompatible type between 'Property' and 'Set(Element)''
I don't know why this is so.

If I use
[property.defaultValue.toString()/] it bring the same output:

org.eclipse.uml2.uml.internal.impl.LiteralRealImpl@d18c0be (name:
> <unset>, visibility: <unset>) (value: 1.0);

However I can not access it via
[property.defaultValue.value.toString()/]

The other
[property.defaultValue.name.toString()/] works but result is always null (When I change the name, instead of the value, the name does not get saved in papyrus)
