Hello everyone,

I have a questions:
I've programmatically created a Parameter, and how can I set the type of
it to Integer?

I've tried as following:
1 Parameter p = UMLFactory.eINSTANCE.createParameter();
2 p.setDirection(ParameterDirectionKind.RETURN_LITERAL);
3 p.setUpper(1);
4 p.setLower(1);
5 LiteralInteger li = UMLFactory.eINSTANCE.createLiteralInteger();
6 li.setValue(3);
7 System.out.println("type" + li.getType().toString());
8 p.setType(li.getType());
9 return p;

but at line 7, the type of "li" is still null??

so how to set the type of a Parameter to a primitive tpye, such as Integer
or String or boolean?

regards
Jinhui

Jinhui,

This question is more appropriate for the UML2 newsgroup (copied).

To progammatically set the type of a parameter, simply call setType(Type),
passing the desired type as an argument.

Additionally, note that a LiteralInteger does not come into existence
knowing that its type is (or even should be) Integer. You will have to
retrieve the Integer primitive type from the UML (or Java) Primitive Types
model library in order to reference it as the parameter's type.

Cheers,

Christian

well, I figured out this Problem too, but the problem now turned to be I
can't load the PrimitiveTypes.
See the other threads from me:

http://www.eclipse.org/newsportal/article.php?id=147&gro up=eclipse.modeling.mdt#147

btw, I am using RSA7.0.0.4.

best regards.
