TAutoIncField is the class created when a dataset must manage 32-bit signed integer data, of datatype ftAutoInc: This field gets it's data automatically by the database engine. It exposes no new properties, but simply overrides some methods to manage 32-bit signed integer data.
It should never be necessary to create an instance of TAutoIncField manually, a field of this class will be instantiated automatically for each auto-incremental field when a dataset is opened.
