Class DisplayData.Identifier

java.lang.Object

org.apache.beam.sdk.transforms.display.DisplayData.Identifier

Enclosing class:

DisplayData

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.
