If an XML Converter application needs to implement customized error handling then it may implement this interface and register it with the Converter object. This may be done either by assigning a ConverterListener to the ConverterFactory in which case all Converters created from that ConverterFactory will share the same instance, or afterwards to an individual Converter, ConvertToXml or ConvertFromXml object.

            
using DDTek.XmlConverter;
namespace Custom {
    class ReportingListener : ConverterListener {

        public void Warning(ConverterException exception) {
            Console.WriteLine(exception.Message);
        }
        public void Error(ConverterException exception) {
            Console.WriteLine(exception.Message);
        }
        public void FatalError(ConverterException exception) {
            Console.WriteLine(exception.Message);
        }

    }
}

Currently, only the EDI converter supports the ConverterListener. If an application registers a ConverterListener with any converter other than an EDI converter, then it will be ignored.
