TShortIntField is instantiated when a dataset must manage a field with 8-bit signed data: the data type ftShortInt. It overrides some methods of TField to handle ShortInt data, and sets some of the properties to values for ShortInt data. It also introduces some methods and properties specific to integer data such as MinValue and MaxValue.
It should never be necessary to create an instance of TShortIntField manually, a field of this class will be instantiated automatically for each integer field when a dataset is opened.
