class PASCALIMPLEMENTATION TFDAggregate : public System::Classes::TCollectionItem

Description

TCollectionItem represents an item in a collection.

FireDAC.Comp.DataSet.TFDAggregate inherits from System.Classes.TCollectionItem. All content below this line refers to System.Classes.TCollectionItem.

TCollectionItem represents an item in a collection.

A TCollection holds a group of TCollectionItem objects. TCollectionItems are created and destroyed by TCollection's Add and Clear methods. Each TCollectionItem has a Collection property that points to the TCollection object to which the item belongs.

Objects descending from TCollection can contain objects descending from TCollectionItem. For example, a TDBGridColumns object contains TColumn objects; these two classes are used by TDBGrid to represent grid columns.
