Examples of org.jfree.report.DataRow

org.jfree.report.DataRow
This is the base interface for all data access collectors. A data-row adds a certain order to the elements in the dataset. It also allows statefull comparisions and data attributes using DataFlags.
The data-row is an internal concept of JFreeReport. The report engine will be responsible for creating and maintaining these implementations. Authors of functions and expressions usually dont have to care where a datarow comes from or at which particular instance they are looking right now.
Note: Do not attempt to cache the datarow outside the core engine. This can have funny sideeffects and might trigger the end of the world. @author Thomas Morgner
