  • Method Summary

    Modifier and Type
    Method
    Description
    void
    fill(int value)
    Fill the column vector with the provided value.
    void
    setInt(int rowId, int value)
    Set int at rowId with the provided value.
    void
    setInts(int rowId, int count, int value)
    Sets value to [rowId, rowId + count) by the value, this is data that repeats continuously.
    void
    setInts(int rowId, int count, int[] src, int srcIndex)
    Sets values from [src[srcIndex], src[srcIndex + count]) to [rowId, rowId + count).
    void
    setIntsFromBinary(int rowId, int count, byte[] src, int srcIndex)
    Set ints from binary, need use UNSAFE to copy.

  • Method Details

    • setInt

      void setInt(int rowId, int value)
      Set int at rowId with the provided value.

    • setIntsFromBinary

      void setIntsFromBinary(int rowId, int count, byte[] src, int srcIndex)
      Set ints from binary, need use UNSAFE to copy.
      Parameters:
      rowId - set start rowId.
      count - count for int, so the bytes size is count * 4.
      src - source binary.
      srcIndex - source binary index, it is the index for byte index.

    • setInts

      void setInts(int rowId, int count, int value)
      Sets value to [rowId, rowId + count) by the value, this is data that repeats continuously.

    • setInts

      void setInts(int rowId, int count, int[] src, int srcIndex)
      Sets values from [src[srcIndex], src[srcIndex + count]) to [rowId, rowId + count).

    • fill

      void fill(int value)
      Fill the column vector with the provided value.
