```
public interface TableSupportsExtraFields
```
Tagging interface to declare a class supports the use of the extraFields member of RowValue. By default, only the keys declared in a schema can be accessed on a Row object. If the Table implements this interface, then other keys can be used and they will access the entries in the extraFields map obtained by RowValue.getExtraFields()
