Description
TNamedItem is the base class for definitions used by datasets.
Data.DB.TFieldDef inherits from Data.DB.TNamedItem. All content below this line refers to Data.DB.TNamedItem.
TNamedItem is the base class for definitions used by datasets.
Use TNamedItem as a base class when defining a class for definitions that are maintained in a collection by a dataset. Sets of TNamedItem objects are maintained by a descendant of TDefCollection that is specific to the type of object defined.
Definition objects are used by datasets to specify the properties of database entities such as fields or indexes.
