    - #### size

          int size()

    - #### get

          double get(int i)

      Gets element from vector by index and cast it to double.
      Parameters:
        `i` - Vector element index.
      Returns:
        Value obtained for given element index.

    - #### getRaw

          <T extends Serializable> T getRaw(int i)

      Type Parameters:
        `T` - Type of stored element in vector.
      Parameters:
        `i` - Vector element index.
      Returns:
        Value obtained for given element index.

    - #### set

          void set(int i,
                   double v)

      Parameters:
        `i` - Vector element index.
        `v` - Value to set at given index.

    - #### setRaw

          void setRaw(int i,
                      Serializable v)

      Parameters:
        `i` - Vector element index.
        `v` - Value to set at given index.

    - #### data

          default double[] data()

      Gets underlying array if `StorageOpsMetrics.isArrayBased()` returns `true` and all values in vector are Numbers. Returns `null` if in other cases.

        `StorageOpsMetrics.isArrayBased()`

    - #### rawData

          default Serializable[] rawData()

      Returns:
        Underlying array of serializable objects `StorageOpsMetrics.isArrayBased()` returns `true`. Returns `null` if in other cases.
