Description
Creates and initializes a TFieldDef instance.
Applications should not call Create directly. A TFieldDef is created automatically by the dataset for each field in an already existing table. When composing field definitions preparatory to creating a new dataset, the TFieldDefs.AddFieldDef method (or the older TFieldDefs.Add method) creates the needed instance of TFieldDef.
