Description

TBytesField is the class used when a dataset must manage data of fixed-size binary type. (TField.DataType equals ftBytes). It initializes some of the properties of the TField class to be able to work with fixed-size byte fields.

It should never be necessary to create an instance of TBytesField manually, a field of this class will be instantiated automatically for each binary data field when a dataset is opened.
