Google BigQuery Table Field Values class, which represents a row in returned query result (table row). Tables rows can be retrieved as a result of a query or when listing table data.

Depending on how a corresponding query was executed, each row (an instance of FieldValueList) may or may not contain related schema. If schema is not provided, the individual cells of the row will still be accessible by index but not by name.
