Class StaticDataRow

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

    public class StaticDataRow
    extends java.lang.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.

                             throws DataSourceException
        Returns the value of the expression or column in the tablemodel using the given column number as index. For functions and expressions, the getValue() method is called and for columns from the tablemodel the tablemodel method getValueAt(row, column) gets called.
        Specified by:
        get in interface DataRow
        Specified by:
