Interface for Provider support |
IProviderSupport is an interface used by Delphi's TProvider (datasnap) technology. It is currently not used in Free Pascal, but is provided for Delphi compatibility. The TDataset class implements all the methods of this interface for the benefit of descendent classes, but does not publish the interface in it's declaration.
