Remarks
The main objective of RowProvider is to provide properly initialized IBufferRow. Usually, derived domain objects require storage in a separate row from the ancestor object. To avoid complicated row initialization, the objects use RowProvider.
Examples
public class Activity: Document { RowProvider ActivityRowProvider; public Activity(Guid id):base(new LoadByIdGetterRowProvider(Table, () => ActivitiesRepository.DocumentIdAttrbute.GetValueForRow(ActivityRowProvider))) { ActivityRowProvider = new LoadByIdRowProvider(Table, id); } public Activity(ObjectTransaction transaction):base(transaction) { ActivityRowService = new NewRowProvider(Table); } public Activity(RowProvider row):base(row.GetReferencedRowProvider(ActivitiesRepository.DocumentReference)) { ActivityRowProvider = row; } //... public void SomeFunc() { var x = ActivityRowService.Row; //... } }
