org.eclipse.nebula.widgets.nattable.summaryrow.SummationSummaryProvider

Implementation of ISummaryProvider that summarizes all values in a column if they are of type Number and return the sum as Double value.

If a column contains mixed values, e.g. Strings and Integers, the SummationSummaryProvider will return {@link ISummaryProvider#DEFAULT_SUMMARY_VALUE} by default, as a summation isnot possible this way. You are able to change that behaviour by creating the SummationSummaryProvider with the parameter strict set to false. In that case the non Number values will be ignored.

            // See the Javadoc for the SummaryRowLayer


            // Default summary provider
            configRegistry.registerConfigAttribute(
                    SummaryRowConfigAttributes.SUMMARY_PROVIDER,
                    new SummationSummaryProvider(this.dataProvider), DisplayMode.NORMAL,
                    SummaryRowLayer.DEFAULT_SUMMARY_ROW_CONFIG_LABEL);


            // Average summary provider for column index 2
            configRegistry.registerConfigAttribute(
                    SummaryRowConfigAttributes.SUMMARY_PROVIDER,
