Constructor Detail

### DataBufferInt

    public DataBufferInt(int size)

  Constructs an integer-based `DataBuffer` with a single bank and the specified size.

  Parameters:
    `size` - The size of the `DataBuffer`.

### DataBufferInt

    public DataBufferInt(int size,
                         int numBanks)

  Constructs an integer-based `DataBuffer` with the specified number of banks, all of which are the specified size.

  Parameters:
    `size` - The size of the banks in the `DataBuffer`.
    `numBanks` - The number of banks in the a`DataBuffer`.

### DataBufferInt

    public DataBufferInt(int[] dataArray,
                         int size)

  Constructs an integer-based `DataBuffer` with a single bank using the specified array. Only the first `size` elements should be used by accessors of this `DataBuffer`. `dataArray` must be large enough to hold `size` elements.

  Parameters:
    `dataArray` - The integer array for the `DataBuffer`.
    `size` - The size of the `DataBuffer` bank.

### DataBufferInt

    public DataBufferInt(int[] dataArray,
                         int size,
                         int offset)

  Constructs an integer-based `DataBuffer` with a single bank using the specified array, size, and offset. `dataArray` must have at least `offset` + `size` elements. Only elements `offset` through `offset` + `size` - 1 should be used by accessors of this `DataBuffer`.

  Parameters:
    `dataArray` - The integer array for the `DataBuffer`.
    `size` - The size of the `DataBuffer` bank.
    `offset` - The offset into the `dataArray`.

### DataBufferInt

    public DataBufferInt(int[][] dataArray,
                         int size)

  Constructs an integer-based `DataBuffer` with the specified arrays. The number of banks will be equal to `dataArray.length`. Only the first `size` elements of each array should be used by accessors of this `DataBuffer`.

  Parameters:
    `dataArray` - The integer arrays for the `DataBuffer`.
    `size` - The size of the banks in the `DataBuffer`.

### DataBufferInt

    public DataBufferInt(int[][] dataArray,
                         int size,
                         int[] offsets)

  Constructs an integer-based `DataBuffer` with the specified arrays, size, and offsets. The number of banks is equal to `dataArray.length`. Each array must be at least as large as `size` + the corresponding offset. There must be an entry in the offset array for each `dataArray` entry. For each bank, only elements `offset` through `offset` + `size` - 1 should be used by accessors of this `DataBuffer`.

  Parameters:
    `dataArray` - The integer arrays for the `DataBuffer`.
    `size` - The size of the banks in the `DataBuffer`.
    `offsets` - The offsets into each array.
