Hi,
I'm trying to set a Property defaultValue to an EnumerationLiteral. However, after the following code has been executed, the enum literal specification value is null, and the default value shows a 0.
Here is xtend code snippet:
val EnumerationLiteral A_LITERAL = // lookup of enumeration literal
val Property p = // lookup of class property (which has a Enumeration as type)
// The following line calls void org.eclipse.uml2.uml.Property.setDefaultValue(ValueSpecification value)
p.defaultValue = A_LITERAL.specification
What is wrong? How do I correctly assign an enumeration literal as a default value?
I'm using an old version of UML2 api (Version: 3.1.2.v201010261927) on IBM RSA 8.0.4.
Thanks a lot!
/Andreas

Hi, Andreas,
Try this:
-------- 8< --------
p.createDefaultValue(null, A_LITERAL.enumeration,
UMLPackage.Literals.INSTANCE_VALUE) as InstanceValue => [
instance = A_LITERAL
]
-------- >8 --------
A value of enumeration type is represented by an InstanceValue, because
EnumerationLiterals are InstanceSpecifications of their Enumeration
types.

Great, that works fine. Here is an excerpt from running code:
(te as Property).createDefaultValue(null, null,
UMLPackage$Literals::INSTANCE_VALUE) as InstanceValue => [
instance = NOSTATUS_LITERAL
]
(I set type parameter to null, in order to get exact same emx encoding as if done by MetaModelAgent GUI.)
Thank you very much for the quick reply!
MVH,
Andreas
