                 Key: JENA-1809
                 URL: https://issues.apache.org/jira/browse/JENA-1809
             Project: Apache Jena

    Affects Versions: Jena 3.13.1
            Reporter: Andy Seaborne
            Assignee: Andy Seaborne


Make {{Iter}} look like stream with common naming and signatures (where it makes sense).

Replace custom interfaces usage with Java8 java.util.* interfaces.

Add operation for iterators that have the coverage of Stream. This includes:
{noformat}
anyMatch
allMatch
noneMatch
findFirst -> Optional
findAny -> Optional
reduce(BinaryConsumer)
min(Comparator)
max(Comparator)
collect(Collector)
{noformat}
