TObjectSource Class

Abstract base class for objects that supply entity records to a TBaseAureliusDataset on demand.

Remarks

Concrete subclasses implement specific fetch strategies. When a paged criteria query is used the dataset creates a TCriteriaSource; when an open cursor is used it creates a TCursorSource. The dataset calls FetchMore repeatedly until Fetching returns False.

Syntax

Unit: Aurelius.Bind.BaseDataset

TObjectSource = class(TObject);
