Class MultiConcat

java.lang.Object

io.smallrye.mutiny.groups.MultiConcat

public class MultiConcat
extends Object

Creates new Multi by concatenating several Multi or Publisher. This class allows configuring how the concatenation is executed. Unlike a merge, a concatenation emits the items in order. Streams are read one-by-one and the items are emitted in this order.

Method Summary

Modifier and Type	Method and Description
MultiConcat	collectFailures() Indicates that the concatenation process should not propagate the first receive failure, but collect them until all the items from all (non-failing) participants have been emitted.
<T> Multi<T>	streams(Iterable<? extends org.reactivestreams.Publisher<T>> iterable) Creates a new Multi concatenating the items emitted by the given multis / publishers..
<T> Multi<T>	streams(org.reactivestreams.Publisher<T>... publishers) Creates a new Multi concatenating the items emitted by the given multis / publishers.

Method Detail

streams

@SafeVarargs
public final <T> Multi<T> streams(org.reactivestreams.Publisher<T>... publishers)

Creates a new Multi concatenating the items emitted by the given multis / publishers.

Type Parameters:

T - the type of item

Parameters:

publishers - the publishers, must not be empty, must not contain null

Returns:

the new Multi emitting the items from the given set of Multi using a concatenation

streams

public <T> Multi<T> streams(Iterable<? extends org.reactivestreams.Publisher<T>> iterable)

Creates a new Multi concatenating the items emitted by the given multis / publishers..

Type Parameters:

T - the type of item

Parameters:

iterable - the publishers, must not be empty, must not contain null, must not be null

Returns:

the new Multi emitting the items from the given set of Multi using a concatenation

collectFailures

public MultiConcat collectFailures()

Indicates that the concatenation process should not propagate the first receive failure, but collect them until all the items from all (non-failing) participants have been emitted. Then, the failures are propagated downstream (as a CompositeException if several failures have been received).

Returns:

this MultiConcat configured to collect the failures.
