Package org.apache.beam.sdk.io.gcp.healthcare

Class DicomIO.ReadStudyMetadata

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.beam.sdk.transforms.display.HasDisplayData
    Enclosing class:
    DicomIO
    public static class DicomIO.ReadStudyMetadata
extends org.apache.beam.sdk.transforms.PTransform<org.apache.beam.sdk.values.PCollection<java.lang.String>,​DicomIO.ReadStudyMetadata.Result>
    This class makes a call to the retrieve metadata endpoint (https://cloud.google.com/healthcare/docs/how-tos/dicomweb#retrieving_metadata). It defines a function that can be used to process a Pubsub message from a DICOM store, read the DICOM study path and get the metadata of the specified study. You can learn how to configure PubSub messages to be published when an instance is stored by following: https://cloud.google.com/healthcare/docs/how-tos/pubsub. The connector will output a DicomIO.ReadStudyMetadata.Result which will contain metadata of the study encoded as a json array.
