OWL API - Store a Class to which an Individual belongs rather than printing it

Question

EntitySearcher.getTypes(individual, ontology) returns a Stream of OWLClassExpression.

to print it we do:

 EntitySearcher.getTypes(individual, ontology).forEach(System.out::println);

Instead i want to store the output in an OWLClass or a Set of OWLClass to deal with it later. How do i do that?

The Stream operations are confusing me.

Sincere regards

To turn a stream into a set, there's a utility in OWLAPIStreamUtils::asSet(Stream) - this is just a convenience around the standard Collectors class.

To get OWLClass only, you need to filter the types:

Set classes = OWLAPIStreamUtils.asSet( EntitySearcher.getTypes(individual, ontology) .filter(OWLClassExpression::isOWLClass));
