All Implemented Interfaces:

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