Constructor Detail

TestSourceStage

public TestSourceStage(GraphStageWithMaterializedValue<SourceShape<T>,M> stageUnderTest,
                       TestProbe probe)

Method Detail

apply

public static <T,M> Source<T,M> apply(GraphStageWithMaterializedValue<SourceShape<T>,M> stageUnderTest,
                                      TestProbe probe)

Creates a source out of the stageUnderTest that will inform the probe of graph stage events and callbacks by sending it the various messages found under GraphStageMessages.

This allows for creation of a "normal" stream starting with the source while still being able to assert internal events.

Parameters:

stageUnderTest - (undocumented)

probe - (undocumented)

Returns:

(undocumented)

named

public static Graph<S,M> named(java.lang.String name)

async

public static Graph<S,M> async()

addAttributes

public static Graph<S,M> addAttributes(Attributes attr)

initialAttributes

protected static Attributes initialAttributes()

module

public static final StreamLayout.Module module()

withAttributes

public static final Graph<S,M> withAttributes(Attributes attr)

out

public Outlet<T> out()

shape

public SourceShape<T> shape()

Description copied from interface: Graph

The shape of a graph is all that is externally visible: its inlets and outlets.

Returns:

(undocumented)

createLogicAndMaterializedValue

public scala.Tuple2<GraphStageLogic,M> createLogicAndMaterializedValue(Attributes inheritedAttributes)
