All known Subclasses:   org.jfree.report.ParameterDataRow,  org.jfree.report.states.datarow.ImportedVariablesDataRow,
StaticDataRow
public class StaticDataRow implements DataRow(Code)
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.
