public DataBufferInt(int size)
DataBuffer with a single bank
and the specified size.
size - The size of the DataBuffer.
public DataBufferInt(int size,
int numBanks)
DataBuffer with the specified number of
banks, all of which are the specified size.
size - The size of the banks in the DataBuffer.numBanks - The number of banks in the aDataBuffer.
public DataBufferInt(int[] dataArray,
int size)
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.
dataArray - The integer array for the DataBuffer.size - The size of the DataBuffer bank.
public DataBufferInt(int[] dataArray,
int size,
int offset)
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.
dataArray - The integer array for the DataBuffer.size - The size of the DataBuffer bank.offset - The offset into the dataArray.
public DataBufferInt(int[][] dataArray,
int size)
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.
dataArray - The integer arrays for the DataBuffer.size - The size of the banks in the DataBuffer.
public DataBufferInt(int[][] dataArray,
int size,
int[] offsets)
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.
dataArray - The integer arrays for the DataBuffer.size - The size of the banks in the DataBuffer.offsets - The offsets into each array.| Method Detail |
