LineDataRecordWriter class

LineDataRecordWriter

Using LineDataRecordWriter requires that the following record format attributes be set:

• Record format ID
• Record format type

In conjunction with the Record or the RecordFormat classes, the LineDataRecordWriter takes a record as input to the writeRecord() method. (Record takes a RecordFormat as input when you instantiate it.)

The LineDataRecordWriter class provides methods that allow you to:

• Get the CCSID
• Get the name of the encoding
• Write the record data, in line data format, to an OutputStream

Example: Using the LineDataRecordWriter class

The following example shows one way to use the LineDataRecordWriter class to write a record:

     // Example using the LineDataRecordWriter class.
        try
        {
          // create a ccsid
          ccsid_ = system_.getCcsid();
          
          // create output queue and specify spooled file data to be *LINE
          OutputQueue outQ = new OutputQueue(system_, "/QSYS.LIB/RLPLIB.LIB/LDRW.OUTQ");
          PrintParameterList parms = new PrintParameterList();
          parms.setParameter(PrintObject.ATTR_PRTDEVTYPE, "*LINE");
          
          // initialize the record format for writing data 
          RecordFormat recfmt = initializeRecordFormat();
        
          // create a record and assign data to be printed...
          Record record = new Record(recfmt);
          createRecord(record);
         
          SpooledFileOutputStream os = null;
          try { 
              // create the output spooled file to hold the record data
              os = new SpooledFileOutputStream(system_, parms, null, outQ);   
          }
          catch (Exception e) {
              System.out.println("Error occurred creating spooled file");
              e.printStackTrace();
          }
           
          // create the line data record writer
          LineDataRecordWriter ldw;
          ldw = new LineDataRecordWriter(os, ccsid_, system_);
          
          // write the record of data
          ldw.writeRecord(record);

          // close the outputstream 
          os.close();
        }

        catch(Exception e)
        {
          failed(e, "Exception occurred.");
        }
