Class DataIterator<T>

  • Type Parameters:
    T - is the output data type returned by this iterator.
    All Implemented Interfaces:, java.lang.AutoCloseable, java.util.Iterator<T>, CloseableIterator<T>

    public class DataIterator<T>

    • Method Detail

      • seek

        public void seek​(int startingFileOffset,
                         long startingRecordOffset)
        (startingFileOffset, startingRecordOffset) points to the next row that reader should resume from. E.g., if the seek position is (file=0, record=1), seek moves the iterator position to the 2nd row in file 0. When next() is called after seek, 2nd row from file 0 should be returned.
      • hasNext

        public boolean hasNext()
        Specified by:
        hasNext in interface java.util.Iterator<T>
