I currently doing some model transformations using EMF-UML-Implementation. In my model transformation I create an uml class with some attributes. The attributes are type of enumerations I also created. Some of the attribute should get a default value. The default value should be enumeration literals.
The question now is, how do I get the enumeration literals to the defaultValue
-property of the Property
.
I already have found that I have to use ValueSpecification
. But the UML superstructure says not much about that (page 139 f.). Which properties do I have to use for setting the defaultValue to enumeration literals?
I think the main problem I have is, that the use of ValueSpecification
is unclear to me. Currently I only use default
to set the default values, which is type of String.
The defaultValue
-property takes a ValueSpecification
argument. So in your case, you need an InstanceValue
for this purpose (which derives from ValueSpecification
). The InstanceValue
itself has an instance
-property, which takes an InstanceSpecification
as argument. As EnumerationLiteral
derives from InstanceSpecification
, you can now simply assign one of your EnumerationLiterals
to it.
