Description

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

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