Class StaticDataRow

  • All Implemented Interfaces:
    Direct Known Subclasses:
    ImportedVariablesDataRow, ParameterDataRow

    public class StaticDataRow
    extends Object
    implements DataRow
    This is a static datarow holding a value for each name in the datarow. This datarow does not hold dataflags and thus does not track the changes done to the data inside.

    The StaticDataRow is a derived view and is used to provide a safe collection of the values of the previous datarow.
