org.apache.derby.iapi.types.SQLSmallint

SQLSmallint satisfies the DataValueDescriptor interfaces (i.e., OrderableDataType). It implements a smallint column, e.g. for storing a column value; it can be specified when constructed to not allow nulls. Nullability cannot be changed after construction, as it affects the storage size and mechanism.

Because OrderableDataType is a subtype of ValueColumn, SQLSmallint can play a role in either a ValueColumn/Row or a OrderableDataType/Row, interchangeably.

We assume the store has a flag for nullness of the value, and simply return a 0-length array for the stored form when the value is null.

PERFORMANCE: There are likely alot of performance improvements possible for this implementation -- it new's Short more than it probably wants to.
