TCollectionItem and TCollection form a pair of base classes that manage a collection of named objects. The TCollectionItem is the named object that is managed, it represents one item in the collection. An item in the collection is represented by three properties: TCollectionItem.DisplayName, TCollection.Index and TCollectionItem.ID.
A TCollectionItem object is never created directly. To manage a set of named items, it is necessary to make a descendant of TCollectionItem to which needed properties and methods are added. This descendant can then be managed with a TCollection class. The managing collection will create and destroy it's items by itself, it should therefore never be necessary to create TCollectionItem descendants manually.
