                            int size)

  Constructs a `double`-based `DataBuffer` with the specified data array. Only the first `size` elements are available for use by this `DataBuffer`. The array must be large enough to hold `size` elements.

Parameters:
  `dataArray` - An array of `double`s to be used as the first and only bank of this `DataBuffer`.
  `size` - The number of elements of the array to be used.

  Constructs a `double`-based `DataBuffer` with the specified data array. Only the elements between `offset` and `offset + size - 1` are available for use by this `DataBuffer`. The array must be large enough to hold `offset + size` elements.

Parameters:
  `dataArray` - An array of `double`s to be used as the first and only bank of this `DataBuffer`.
  `size` - The number of elements of the array to be used.
  `offset` - The offset of the first element of the array that will be used.

  Constructs a `double`-based `DataBuffer` with the specified data arrays, size, and per-bank offsets. The number of banks is equal to dataArray.length. Each array must be at least as large as `size` plus the corresponding offset. There must be an entry in the `offsets` array for each data array.

Parameters:
  `dataArray` - An array of arrays of `double`s to be used as the banks of this `DataBuffer`.
  `size` - The number of elements of each array to be used.
