Class CompositionStreamId<X,T>

java.lang.Object

org.streamingpool.core.service.streamid.CompositionStreamId<X,T>

Type Parameters:

X - The type of objects emitted by the source ReactiveStreams.

T - The type of objects emitted by the new created ReactiveStream.

All Implemented Interfaces:

StreamId<T>

public final class CompositionStreamId<X,T>
extends java.lang.Object
implements StreamId<T>

Generic implementation of StreamId which in conjunction with the CompositionStreamFactory allows for the easy creation of general purpose streams based on composition of streams. This class is experimental.
