Purpose: An item specifying a class constructor method to be used in a ReportQuery's returned results. Example: ConstructorReportItem citem = new ConstructorReportItem("Employee"); citem.setResultType(Employee.class); citem.addAttribute("firstName", employees.get("firstName")); query.addConstructorReportItem(citem); when executed will return a collection of ReportQueryResults that contain Employee objects created using the new Employee(firstname) method.
