  • Method Details

    • get

      public byte get(long index)
      Description copied from interface: ByteVector
      Get the element of this ByteVector at offset index. If index is not within range [0, size()), will return the null byte.
      Parameters:
      index - An offset into this ByteVector
      Returns:
      The element at the specified offset, or the null byte

    • subVector

      public ByteVector subVector(long fromIndexInclusive, long toIndexExclusive)
      Description copied from interface: Vector
      Get a Vector that represents a slice of this Vector.
      Parameters:
      fromIndexInclusive - The first offset into this Vector to include in the result; if negative, the result will have a range of null values at offsets in [0, -fromIndexInclusive)
      toIndexExclusive - The first offset into this Vector to not include in the result; if larger than size(), the result will have a range of null values at the corresponding offsets
      Returns:
      The sub-Vector specified by [fromIndexInclusive, toIndexExclusive)

    • subVectorByPositions

      public ByteVector subVectorByPositions(long[] positions)
      Description copied from interface: Vector
      Get a Vector that represents a set of offset positions in this Vector.
      Parameters:
      positions - The offsets to include; if not within [0, size()), the corresponding offset in the result will contain the appropriate null value
      Returns:
      The sub-Vector specified by positions

    • size

      public long size()
      Description copied from interface: LongSizedDataStructure
      The size of this data structure.
      Returns:
      The size
