final class Partition[T] extends GraphStage[UniformFanOutShape[T, T]]

Fan-out the stream to several streams. emitting an incoming upstream element to one downstream consumer according to the partitioner function applied to the element

Emits when emits when an element is available from the input and the chosen output has demand

Backpressures when the currently chosen output back-pressures

Completes when upstream completes and no output is pending

Cancels when all downstreams have cancelled (eagerCancel=false) or one downstream cancels (eagerCancel=true)

Value Members

  1. def addAttributes(attr: Attributes): Graph[UniformFanOutShape[T, T], NotUsed]

    Add the given attributes to this Graph.

    Add the given attributes to this Graph. If the specific attribute was already present on this graph this means the added attribute will be more specific than the existing one. If this Source is a composite of multiple graphs, new attributes on the composite will be less specific than attributes set directly on the individual graphs of the composite.
