Class FilterRowRegularExpressionConverter

java.lang.Object
org.eclipse.nebula.widgets.nattable.data.convert.DisplayConverter
org.eclipse.nebula.widgets.nattable.filterrow.FilterRowRegularExpressionConverter
All Implemented Interfaces:
IDisplayConverter
public class FilterRowRegularExpressionConverter extends DisplayConverter
IDisplayConverter that is intended to be used for filter row editors that are configured for regular expression evaluation. It will add simplified usage of wildcards for end users by replacing * to the regular expression (.*) and ? to the regular expression (.?).

Note:
As the characters * and ? are replaced to match the corresponding regular expression using this IDisplayConverter will suppress the ability to search for those characters completely. If it should be supported to search for those wildcards, implement a custom converter that supports to mask the icons or stick with the default regular expression syntax.

Note:
The FilterRowRegularExpressionConverter needs to be registered as CellConfigAttributes.DISPLAY_CONVERTER! 
 configRegistry.registerConfigAttribute(
         CellConfigAttributes.DISPLAY_CONVERTER,
         new FilterRowRegularExpressionConverter(),
         DisplayMode.NORMAL,
         FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX
                 + DataModelConstants.FIRSTNAME_COLUMN_POSITION);
