Description
Interface that extends a TDataSet descendent class to support additional commands.
The IDataSetCommandSupport interface is used to extend a TDataSet descendent class to support additional commands. Datasnap.DBClient.TClientDataSet is extended to support the ApplyUpdates and CancelUpdates commands.
TDBNavigator uses IDataSetCommandSupport to access ApplyUpdates and CancelUpdates commands of a Datasnap.DBClient.TClientDataSet without referencing the Datasnap.DBClient.TClientDataSet type. This design allows TDBNavigator to execute commands on Datasnap.DBClient.TClientDataSet without referencing the Datasnap.DBClient.TClientDataSet.
Other components can use this interface to access the extended commands.
