Parsing Rules

Please follow the Parsing Rules example given in the data directory of the repository. Mapping Rules should follow below model class structure

                                
                                    public class MappingRules
                                    {
                                        public string Namespace { get; set; }
                                        public List Mappings { get; set; }
                                    }

                                    public class MappingTable
                                    {
                                        public string NodeName { get; set; }
                                        public string XPath { get; set; }
                                        public IList Columns { get; set;}
                                    }

                                    public class MappingColumn
                                    {
                                        public int OrderNumber { get; set; }
                                        public string NodeName { get; set; }
                                        public string XPath { get; set; }
                                        public string DataType { get; set; }
                                        public int MinLength { get; set; }
                                        public int MaxLength { get; set; }
                                        public int fractionDigits { get; set; }
                                        public int totalDigits { get; set; }
                                    }
                                
                            

Override the Parsing Rules

The given example is in json file. Suppose you want to store Parsing rules in Database. Now you need to override the ParsingRules class method DeserializeRules.

                                
                                    public class ParsingDatabaseRules : ParsingRules
                                    {
                                        public override void DeserializeRules()
                                        {
                                        //MapParsingRules is of type IList?
                                            MapParsingRules = GetMyRulesFromDB();
                                        }
                                    }
