    • RangeIterator

      public RangeIterator(RunEndEncodedVector runEndEncodedVector, int startIndex, int length)
      Constructs a new RangeIterator for iterating over a range of values in a RunEndEncodedVector.
      Parameters:
      runEndEncodedVector - The vector to iterate over
      startIndex - The logical start index of the range (inclusive)
      length - The number of values to include in the range
      Throws:
      IllegalArgumentException - if startIndex is negative or (startIndex + length) exceeds vector bounds

  • Method Details

    • nextRun

      public boolean nextRun()
      Advances to the next run in the range.
      Returns:
      true if there is another run available, false if iteration has completed

    • nextValue

      public boolean nextValue()
      Advances to the next value in the range.
      Returns:
      true if there is another value available, false if iteration has completed

    • getRunIndex

      public int getRunIndex()
      Gets the current run index (physical position in the run-ends vector).
      Returns:
      the current run index

    • getRunLength

      public int getRunLength()
      Gets the length of the current run within the iterator's range.
      Returns:
      the number of remaining values in current run within the iterator's range

    • isEnd

      public boolean isEnd()
      Checks if iteration has completed.
      Returns:
      true if all values in the range have been processed, false otherwise
