StaticDataRow (flow-engine JavaDoc)

Class StaticDataRow

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.
