An annotation is a top level function that returns a subtype of ConstrainedAnnotation.
There are 2 interfaces which satisfy ConstrainedAnnotation directly:
- OptionalAnnotation: An annotation that may occur at most once at a single program element and only on certain program elements.
- SequencedAnnotation: An annotation that may occur multiple times at a single program element, and only on certain program elements.
Let's see the type hierarchy of ConstrainedAnnotation to get a better picture.

In this demo we have 2 Case Providers, one for Activiti and one for WPS. I used Thread.sleep to mimic a time consuming computation (e.g. IO). Now we want to have a composite Case Provider which composes cases from both case providers. However, as we naively implement this in SequentialCaseProvider we will see that the total time it takes is the sum of having the 2 caseproviders fetch the cases (9 seconds). By using a concurrent approach in ConcurrentCaseProvider, we can reduce the time to +- the time it takes the longest CaseProvider to fetch the cases. (5 seconds)
