Abstract Value Members

  1. abstract def generateIndex(dataStream: SimpleStream, headerStream: SimpleStream, fileNumber: Int, isRdwBigEndian: Boolean): ArrayBuffer[SparseIndexEntry]

    Permalink

    Traverses the data sequentially as fast as possible to generate record index.

    Traverses the data sequentially as fast as possible to generate record index. This index will be used to distribute workload of the conversion.

    dataStream

    A stream of input binary data

    headerStream

    A stream pointing to the beginning of the file, even if inputStream is pointing to a record in the middle.

    fileNumber

    A file number uniquely identified a particular file of the data set

    returns

    An index of the file

  3. abstract def getRecordIterator(dataStream: SimpleStream, headerStream: SimpleStream, startingFileOffset: Long, fileNumber: Int, startingRecordIndex: Long): Iterator[Seq[Any]]

    Permalink

    Returns a file iterator between particular offsets.

    Returns a file iterator between particular offsets. This is for faster traversal of big binary files

    dataStream

    A stream positioned at the beginning of the intended file portion to read

    headerStream

    A stream pointing to the beginning of the file, even if inputStream is pointing to a record in the middle.

    startingFileOffset

    An offset of the file where parsing should be started

    fileNumber

    A file number uniquely identified a particular file of the data set

    startingRecordIndex

    A starting record index of the data

    returns

    An iterator of Spark Row objects

    Returns true if index generation is requested

  6. abstract def isRdwBigEndian: Boolean

    Permalink

    Returns true if RDW header of variable length files is big endian
