final class MergePrioritized[T] extends GraphStage[UniformFanInShape[T, T]]

Merge several streams, taking elements as they arrive from input streams (picking from prioritized once when several have elements ready).

A MergePrioritized has one out port, one or more input port with their priorities.

Emits when one of the inputs has an element available, preferring a input based on its priority if multiple have elements available

Backpressures when downstream backpressures

Completes when all upstreams complete (eagerComplete=false) or one upstream completes (eagerComplete=true), default value is false

Cancels when downstream cancels

    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.
