org.openfaces.component.table.Summary

The same Summary component can be rendered in different places depending on how it is declared. If it is declared in the table's "header"/"footer" facet or the column's "header"/"footer" facet then the value for this Summary component is calculated over all displayed rows, and it is rendered only once in the table's/column's header/footer. In this case, such Summary is called a "global" one. But it can also be placed into one of the grouping-related facets of the tag, which will make the component to be rendered several times -- once for each group (according to the facet in which it is declared). In this case, we have to maintain several summary value calculator objects -- one for each RowGroup (which is identical to "one per each time it is rendered"). This object contains all of the info for such single rendering instance.

    public void encodeBegin(FacesContext context, UIComponent component) throws IOException {
        Summary summary = (Summary) component;
        ResponseWriter writer = context.getResponseWriter();
        writer.startElement("span", summary);
        writeIdAttribute(context, summary);
        Rendering.writeStyleAndClassAttributes(writer, summary);
        Rendering.writeStandardEvents(writer, summary);
