Examples of JRVariable

net.sf.jasperreports.engine.JRVariable
An interface for implementing classes that deal with report variables. This interface defines constants for names of built-in variables and for reset, increment and calculation types.
When declaring a report group, the engine will automatically create a count variable that will calculate the number of records that make up the current group (number of records processed between group ruptures). The name for this variable comes from the name of the group it corresponds to, suffixed with the "_COUNT" sequence. It can be used like any other report variable, in any report expression (even in the current group expression like you can see done in the "BreakGroup" of the jasper sample). @author Teodor Danciu (teodord@users.sourceforge.net) @version $Id: JRVariable.java 3583 2010-03-12 11:35:40Z shertage $
