TextRecordExtractor

class TextRecordExtractor extends Serializable with RawRecordExtractor

This implementation of a record extractor for ASCII test files.

Record extractors are used for in situations where the size of records in a file is not fixed and cannot be determined neither from the copybook nor from record headers.

Empty lines (ones that contain only LF / CRLF) are skipped.

The implementation is optimized for performance, so might be not obviously readable. Hopefully, comments will help anyone reading this.

    Returns true if the input stream can be split at the given location.

    Usually every file can be split by the location at the beginning of each record. However, block variable length files (record_format = VB) can only be split by blocks

  64. def offset: Long

    Returns the byte offset of the next record.

    Returns the byte offset of the next record.

    The offset should point to the absolute beginning of the record, e.g. including headers, so that if a record extractor is started from this offset it would be able to extract the record by invoking .next().

    IMPORTANT. The offset points to the next record to be fetched by .next(). If this invariant is not held, the reader might get inconsistent record ids, or can fail in certain circumstances.

    If you want to prefetch a record, use this pattern:

    class ExampleRecordExtractor(ctx: RawRecordContext) extends Serializable with RawRecordExtractor {

  private var currentOffset = ctx.inputStream.offset

  var record: Option[Array[Byte]] = fetchRecord()

  override def offset: Long = currentOffset

  override def hasNext: Boolean = record.isDefined

  override def next(): Array[Byte] = {
    if (record.isEmpty)
        throw new NoSuchElementException("next on empty iterator")

    currentOffset = ctx.inputStream.offset
    val result = record.get
    record = fetchRecord()
    result
  }

  def fetchRecord(): Option[Array[Byte]] = {
    // fetch the record from the stream if any
  }
}

    Clients of 'spark-cobol' can pass additional information to custom record header parsers using

    .option("re_additional_info", "...anything as a string...")

    If a client provides any additional info the method will be executed just after constructing the record header parser.

    Built-in record header parsers ignore the additional info. This info string is intended for custom record header parsers.

    additionalInfo

    A string provided by a client for the record header parser.
