C++ Implementation

The C++ implementation is composed of the source files listed below.

• X12ToXML.cpp : the main routine for the C++ application with an X12 interchange as source

• X12SourceConverter.cpp : the class that drives conversion from X12 to XML

• X12SourceConverter.h : the header file for the X12SourceConverter class

• EDIRecordReader.cpp : the class that handles reading EDI segments and converting to XML

• EDIRecordReader.h : the header file for the EDIRecordReader class

• X12RecordReader.cpp : the class that handles reading X12 control segments

• X12RecordReader.h : the header file for the X12RecordReader class

• XMLToX12.cpp : the main routine for the C++ application with an X12 interchange as the target

• X12TargetConverter.cpp : the class that drives conversion from XML to an X12 interchange

• X12TargetConverter.h : the header file for the X12TargetConverter class

• EDIRecordWriter.cpp : the class that handles reading XML and building and writing EDI segments

• EDIRecordWriter.h : the header file for the EDIRecordWriter class

• X12RecordWriter.cpp : the class that handles building and writing X12 control segments

• X12RecordWriter.h : the header file for the X12RecordWriter class

• DataCellX12N.cpp : the class that handles the X12 Number data type

• DataCellX12N.h : the header file for the DataCellX12N class

• DataCellX12R.cpp : the class that handles the X12 Decimal data type

• DataCellX12R.h : the header file for the DataCellX12R class

• DataCellX12DT.cpp : the class that handles the X12 Date data type

• DataCellX12DT.h : the header file for the DataCellX12DT class

• DataCellX12TM.cpp : the class that handles the X12 Time data type

• DataCellX12TM.h : the header file for the DataCellX12TM class

The writeISA method uses the time and localtime functions from time.h to get the date and time for the interchange and group headers.

 // Set time zone from TZ environment variable. If TZ is not set, // the operating system is queried to obtain the default value // for the variable. // tzset(); // Get System Time time( &ltime ); today = localtime( &ltime ); sprintf(cYear,"%d",(today->tm_year + 1900)); sprintf(cMonth,"%02d",(today->tm_mon + 1)); sprintf(cDay,"%02d",(today->tm_mday )); sprintf(cHour,"%02d",(today->tm_hour )); sprintf(cMinute,"%02d",(today->tm_min )); 

The X12RecordReader's methods that parse control segments use the familiar C strtok function.
