Methods' Summary
getTypes returns a sequence of all types (usually interface types) provided by the object. Important: If the object aggregates other objects the sequence also has to contain all types supported by the aggregated objects.  
getImplementationId returns a sequence of bytes with length > 0 that is used as an Id to distinguish unambiguously between two sets of types, e.g. to realise hashing functionality when the object is introspected. Two objects that return the same UUID also have to return the same set of types in getTypes(). If a unique implementation Id cannot be provided this method has to return an empty sequence. Important: If the object aggregates other objects the UUID has to be unique for the whole combination of objects.
