Description

TDefCollection holds the definition objects (TNamedItem) that represent the specifications for database entities such as fields or indexes.

TDefCollection is used as a base class for collections of definition objects such as index or field definitions. TTable objects and TClientDataSet objects use these definition objects to specify the attributes of a database entity before creating the underlying table or dataset.

Use the properties and methods of TDefCollection to:

Access a specific definition object.

Add or delete definition objects from the list.

Find out how many definition objects are defined.

Copy a set of definitions to another dataset.
