Class RoundRobinStreamCombiner<T>

java.lang.Object

org.openimaj.util.stream.AbstractStream<T>

org.openimaj.util.stream.combine.RoundRobinStreamCombiner<T>

Type Parameters:

T - Type of items in the streams being combined

All Implemented Interfaces:

Iterable<T>, Iterator<T>, Stream<T>

public class RoundRobinStreamCombiner<T>
extends AbstractStream<T>

Given a List of streams of a given type, present a stream of that type which asks each stream in the List for an item in turn. If any stream in the List says it has no item, this Stream will report it has no item and likely stop processing all streams. The specifics of this behaviour are that if when it comes to a stream's turn to provide an item it fails to do so, all the streams will stop being asked simultaneously.
