Hi All,
in the OCL standard description there is an information that OCL
expression may be used as an initialization expression for UML class
attributes. I suppose that in such case Property's defaultValue is set
to ExpressionInOCL object.
My question is how are the types and values mapped between OCL and
UML. If we have a Property that is a collection ( dogs:Dog[0..*] ) are
the values from a resulting OCL matched automatically?
This question has a little deeper meaning for me. If we use
ExpressionInOCL as a ValueSpecification in a UML Action (for example
ValueSpecificationAction) and we need to use OutputPin and ObjectFlow
to actually consume resulting values. How is the OCL collection
interpreted then?
Thanks in advance,
Krzysztof
