TDefCollection is a parent class for the TFieldDefs and TIndexDefs collections: It holds a set of named definitions on behalf of a TDataset component. To this end, it introduces a dataset property, and a mechanism to notify the dataset of any updates in the collection. It is supposed to hold items of class TNamedItem, so the TDefCollection.Find method can find items by named.
