Class MultiMerge

java.lang.Object

io.smallrye.mutiny.groups.MultiMerge

public class MultiMerge
extends Object

Creates new Multi by merging several Multi or Publisher. This class allows configuring how the merge is executed. Unlike a concatenation, a merge emits the items as they come, so the items may be interleaved.

Method Summary

Modifier and Type	Method and Description
MultiMerge	collectFailures() Indicates that the merge 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<org.reactivestreams.Publisher<T>> iterable) Creates a new Multi merging the items emitted by the given publishers / publishers.
<T> Multi<T>	streams(org.reactivestreams.Publisher<T>... publishers) Creates a new Multi merging the items emitted by the given multis / publishers.
MultiMerge	withConcurrency(int concurrency) Indicates that the merge process can consume up to concurrency streams in parallel.
MultiMerge	withRequests(int requests) Indicates that the merge process should consume the different streams using the given request.

Method Detail

streams

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

Creates a new Multi merging 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

streams

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

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

Type Parameters:

T - the type of item

Parameters:

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

Returns:

the new Multi emitting the items from the given set of Publisher

collectFailures

public MultiMerge collectFailures()

Indicates that the merge 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:

a new MultiMerge collecting failures

withRequests

public MultiMerge withRequests(int requests)

Indicates that the merge process should consume the different streams using the given request.

Parameters:

requests - the request

Returns:

a new MultiMerge configured with the given requests

withConcurrency

public MultiMerge withConcurrency(int concurrency)

Indicates that the merge process can consume up to concurrency streams in parallel. Items emitted by these streams may be interleaved in the resulting stream.

Parameters:

concurrency - the concurrency

Returns:

a new MultiMerge configured with the given concurrency
