DisplayData.Identifier (Google Cloud Dataflow SDK 1.9.1 API)

Google Cloud Dataflow SDK for Java, version 1.9.1


Class DisplayData.Identifier

  • java.lang.Object
    • com.google.cloud.dataflow.sdk.transforms.display.DisplayData.Identifier
  • Enclosing class:

    public static class DisplayData.Identifier
    extends Object
    Unique identifier for a display data item within a component. Identifiers are composed of the key they are registered with and a namespace generated from the class of the component which registered the item.

    Display data registered with the same key from different components will have different namespaces and thus will both be represented in the composed DisplayData. If a single component registers multiple metadata items with the same key, only the most recent item will be retained; previous versions are discarded.
