public class PageSumFunction
extends org.jfree.report.function.AbstractFunction
implements java.io.Serializable, org.jfree.report.event.PageEventListener

A JFreeReport function that will sum a field not by group and not by report but by page. That is, if there are 10 items, listed 5 per page, then this sum function can be used to print the sum of the first five items of a specific numeric field on the first page. On the second page the sum will appear again but this time it will be the sum of the next five items.
