    Description

    TRowStateValue is an enumeration type with values that indicate the state for field values in the row. Values in the enumeration indicate how fields in an update buffer differ from the fields in the original record data. Values from TRowStateValue are stored in the TRowState type, and used in data packet readers for TBufDataset (TDataPacketReader).
