You can import existing type libraries into IBM® Rational® Rhapsody® so that elements can reference them. The resulting structure is a Rational Rhapsody package that reflects the type library, its interfaces, and coclasses. A package that is the result of a type library import is read-write, but code generation is disabled for it.
If you implement COM servers, you can use an imported type library package as the basis for deriving new interfaces. If you implement COM clients, you can use the type library to interact with external TLB interfaces. See TLB importer for information about how to use the Rational Rhapsody TLB importer.
