Hi Jürgen,
thank you for your feedback. It has clarified some things for me, but
also one point is still up: XTypeDescriptionEnumerationAccess
.createTypeDescriptionEnumeration() seems not to work as "announced in
the docs": the enumeration can be restricted if one supplies a sequence
of TypeClass values. Whenever I try to do that, an empty enumeration is
created (I would be intrested in interfaces and services only).
Created another Java program version to demonstrate the effect:
