Constructor Detail

FlatMapOperation

public FlatMapOperation(Function<? super I,? extends Stream<? extends O>> function)

Method Detail

perform

public Stream<O> perform(Stream<I> stream)

Description copied from interface: IntermediateOperation

Performs the actualy intermediate operation returning the resulting stream

Specified by:

perform in interface IntermediateOperation<I,Stream<I>,O,Stream<O>>

Parameters:

stream - the stream to have the operation performed on

Returns:

the resulting stream after the operation was applied

getFunction

public Function<? super I,? extends Stream<? extends O>> getFunction()

handleInjection

public void handleInjection(ComponentRegistry registry)

Description copied from interface: IntermediateOperation

Handles injection of components for various dependencies that the intermediate operation has

Specified by:

handleInjection in interface IntermediateOperation<I,Stream<I>,O,Stream<O>>

Parameters:

registry - the registry to use

map

public Stream<Stream<O>> map(Stream<I> iStream)

Description copied from interface: FlatMappingOperation

Instead of flat mapping this returns a stream of OutputStream.

Specified by:

map in interface FlatMappingOperation<I,Stream<I>,O,Stream<O>>

Parameters:

iStream - the stream to convert

Returns:

the stream of streams

mapFlowable

public io.reactivex.rxjava3.core.Flowable<O> mapFlowable(io.reactivex.rxjava3.core.Flowable<I> input)

Description copied from interface: IntermediateOperation

Performs the intermediate operation on a Flowable. This is an interop method to allow Distributed Streams to actually use Distributed Publisher

Specified by:

mapFlowable in interface IntermediateOperation<I,Stream<I>,O,Stream<O>>

Parameters:

input - the input flowable

Returns:
