jimm.datavision.ParameterReader
| ParameterReader | | public class ParameterReader extends DefaultHandler (Code) | | A parameter reader reads an XML file and sets a
Report 's parameter
values. This class is used when the report is being run from the
command line and the user has given us the name of an XML file containing
parameter elements.
Unlike a
ReportReader , a parameter reader's constructor
takes not only the report but also the input method (file name, stream,
or reader). That way the report object doesn't have to know how to hold
on to those multipule input types.
