Class HL7v2IO.Read

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.beam.sdk.transforms.display.HasDisplayData
    Enclosing class:
    HL7v2IO
    public static class HL7v2IO.Read
extends org.apache.beam.sdk.transforms.PTransform<org.apache.beam.sdk.values.PCollection<java.lang.String>,​HL7v2IO.Read.Result>
    The type Read that reads HL7v2 message contents given a PCollection of message IDs strings.

    These could be sourced from any PCollection of Strings but the most popular patterns would be PubsubIO.readStrings() reading a subscription on an HL7v2 Store's notification channel topic or using HL7v2IO.ListHL7v2Messages to list HL7v2 message IDs with an optional filter using Ingest write method. @see .
