Class IteratorOfJenaSets<E>

java.lang.Object

org.apache.jena.util.iterator.NiceIterator<E>

org.apache.jena.mem.iterator.IteratorOfJenaSets<E>

Type Parameters:

E - the element type of the inner sets

All Implemented Interfaces:

Iterator<E>, org.apache.jena.atlas.iterator.IteratorCloseable<E>, org.apache.jena.atlas.lib.Closeable, ClosableIterator<E>, ExtendedIterator<E>

public class IteratorOfJenaSets<E>
extends NiceIterator<E>

Flat-map style iterator that yields every element of every JenaSet produced by the given parent iterator. Empty inner sets are silently skipped. Equivalent in spirit to a one-level flatMap but tailored to the JenaSet API and to NiceIterator.
