java.lang.Object

org.apache.beam.sdk.coders.Coder<T>

org.apache.beam.sdk.coders.StructuredCoder<K>

org.apache.beam.runners.dataflow.internal.IsmFormat.MetadataKeyCoder<K>

All Implemented Interfaces:

Serializable

Enclosing class:

IsmFormat

public static class IsmFormat.MetadataKeyCoder<K>
extends StructuredCoder<K>

A coder for metadata key component. Can be used to wrap key component coder allowing for the metadata key component to be used as a place holder instead of an actual key.
