@CheckReturnValue
public MultiItemCombineIterable streams(Iterable<? extends Flow.Publisher<?>> iterable)

Combines the items from multiple streams.

If you pass no publishers, the resulting Multi emits the completion event immediately after subscription. If you pass a single publisher, it calls the combination logic for every item from this stream (wrapped in a list of a single element). The resulting Multi emits the result from that combination logic. If you pass multiple publishers, it calls the combination logic for every group of items (1 per upstream publisher) wrapped in a list. The resulting Multi emits the result of that combination logic.

As soon as one of the publisher completes, the combination completes and the completion event is emitted. If any of the publisher emits a failure, the failure is passed downstream and the combination stops.

Parameters:

iterable - the iterable containing the streams to combine. Must not be null

Returns:

the object to configure the combination process
