Class MapError<T>

  • All Implemented Interfaces:
    Graph<FlowShape<T,​T>,​NotUsed>, java.io.Serializable, scala.Equals, scala.Product, scala.Serializable
    public final class MapError<T>
extends GraphStages.SimpleLinearGraphStage<T>
implements scala.Product, scala.Serializable
    Maps error with the provided function if it is defined for an error or, otherwise, passes it on unchanged.

    While similar to Recover this operator can be used to transform an error signal to a different one *without* logging it as an error in the process. So in that sense it is NOT exactly equivalent to recover(t => throw t2) since recover would log the t2 error.
