Examples of org.displaytag.render.TableTotaler

org.displaytag.render.TableTotaler
This class just keeps a running grouped total. It does not output anything; it is the responsibility of the exporter or of the decorator to actually output the results. @author rapruittDate: May 21, 2010 Time: 9:17:43 PM

    public void setModel(TableModel m)
    {
        m.setTableDecorator(NOOP);
