TCursorSource Class

A Aurelius.Bind.BaseDataset.TObjectSource that fetches entity objects one at a time through an open database cursor.

Remarks

Objects are fetched on demand as the dataset scrolls forward. The cursor remains open until all records have been consumed or the dataset is closed. The cursor interface is reference-counted and released automatically when it is no longer needed. Use SetSourceCursor on TCustomAureliusDataset to create this source indirectly.
