All Implemented Interfaces:
Serializable, Cloneable, Comparable<RowId>
public final class Row extends RowId implements Serializable, Cloneable
The data of a single row in a table (keys/values form a map), or of multiple rows with the same id (values is an array of Serializable).

The id of the row is distinguished internally from other columns. For fragments corresponding to created data, the initial id is a temporary one, and it will be changed after database insert.
