Type Members

1. final class Accumulate[A, B] extends GraphStage[FlowShape[A, B]]

   

   This stage emits folded values like scan, but the first element emitted is not the zero value but the result of applying the given function to the given zero value and the first pushed element.

   A

   input type

   B

   output type

2. final class AccumulateWhileUnchanged[Element, Property] extends GraphStage[FlowShape[Element, Seq[Element]]]

   

   Accumulates elements of type Element while a property extracted with propertyExtractor remains unchanged, emits an accumulated sequence when the property changes

   Accumulates elements of type Element while a property extracted with propertyExtractor remains unchanged, emits an accumulated sequence when the property changes

   Element

   type of accumulated elements

   Property

   type of the observed property

3. final class DirectoryChanges extends GraphStage[SourceShape[Pair[Path, Change]]]

   

4. final class FileTailSource extends GraphStage[SourceShape[ByteString]]

   

5. final class LastElement[A] extends GraphStageWithMaterializedValue[FlowShape[A, A], Future[Option[A]]]

   

   This stage materializes to the last element pushed before upstream completion, if any, thereby recovering from any failure.

   This stage materializes to the last element pushed before upstream completion, if any, thereby recovering from any failure. Pushed elements are just passed along.

   A

   input and output type

6. final class PartitionWith[In, Out0, Out1] extends GraphStage[FanOutShape2[In, Out0, Out1]]

   

   This stage partitions input to 2 different outlets, applying different transformations on the elements, according to the received partition function.

   This stage partitions input to 2 different outlets, applying different transformations on the elements, according to the received partition function.

   In

   input type

   Out0

   left output type

   Out1

   right output type

7. trait TimedIntervalBetweenOps extends AnyRef

   

   Provides operations needed to implement the timedIntervalBetween DSL

8. trait TimedOps extends AnyRef

   

   Provides operations needed to implement the timed DSL

9. final class ZipInputStreamSource extends GraphStageWithMaterializedValue[SourceShape[(ZipEntryData, ByteString)], Future[Long]]

   

   A stage that works as a Source of data chunks extracted from zip files.

   A stage that works as a Source of data chunks extracted from zip files. In addition to regular files, the zip file might contain directories and other zip files. Every chunk is a tuple of ZipEntryData and ByteString, where the former carries basic info about the file from which the bytes come and the latter carries those bytes. This stage materializes to the total amount of read bytes.
