6.6. Parameters

A report can declare a number of parameters. Parameters represent named object references that are passed-in to the report engine before the execution of the report. These parameters can be used to provide additional information unknown at the moment of report creation. Once declared, parameters can be referred to in expressions using a dedicated syntax. JasperAssistant groups these declarations under a single Parameters node in the Outline View. New parameters can be added by using the context menu associated to this node.
