A. Soroka commented on JENA-1427: --------------------------------- I'd be very much inclined to just {{nextOptional}}. It's simple and it reuses a standard type which is already familiar to users. It provides all the functionality in that type, so or-else and more. > Add nextOrElse() method in ExtendedIterator > ------------------------------------------- > > Key: JENA-1427 > URL: https://issues.apache.org/jira/browse/JENA-1427 > Project: Apache Jena > Issue Type: Improvement > Components: Core > Affects Versions: Jena 3.5.0 > Reporter: Adam Jacobs > Priority: Trivial > Labels: easytask > > Allow a functional approach for returning a default value or throwing a > custom exception from a Jena iterator. > The following method may be added to the ExtendedIterator interface. > {noformat} > /** > Answer the next object, if it exists, otherwise invoke the > _supplier_. > */ > public default T nextOrElse( Supplier<T> supplier ) { > return hasNext() ? next() : supplier.get(); > } > {noformat} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
