Examples of SQLBoolean

org.apache.derby.iapi.types.SQLBoolean
SQLBoolean satisfies the DataValueDescriptor interfaces (i.e., DataType). It implements a boolean 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 DataType is a subtype of DataType, SQLBoolean can play a role in either a DataType/Row or a DataType/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 Integer more than it probably wants to.
