DataBufferInt(int size)
Creates a new data buffer with a single data bank containing the
specified number of
int elements. |
DataBufferInt(int[][] dataArray,
int size)
Creates a new data buffer backed by the specified data banks.
|
DataBufferInt(int[][] dataArray,
int size,
int[] offsets)
Creates a new data buffer backed by the specified data banks, with
the specified offsets to the first element in each bank.
|
DataBufferInt(int[] dataArray,
int size)
Creates a new data buffer backed by the specified data bank.
|
DataBufferInt(int[] dataArray,
int size,
int offset)
Creates a new data buffer backed by the specified data bank, with
the specified offset to the first element.
|
DataBufferInt(int size,
int numBanks)
