Row (Apache Beam 2.6.0)

java.lang.Object
- org.apache.beam.sdk.values.Row

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

RowWithGetters, RowWithStorage
```
@Experimental
public abstract class Row
extends java.lang.Object
implements java.io.Serializable
```
Row is an immutable tuple-like schema to represent one element in a PCollection. The fields are described with a Schema.
Schema contains the names for each field and the coder for the whole record, {see @link Schema#getRowCoder()}.
