public DataBufferShort(int size)
DataBuffer
with a single bank and the
specified size.
size
- The size of the DataBuffer
.public DataBufferShort(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 DataBufferShort(short[] 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 short array for the DataBuffer
.size
- The size of the DataBuffer
bank.public DataBufferShort(short[] 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 short array for the DataBuffer
.size
- The size of the DataBuffer
bank.offset
- The offset into the dataArray
.public DataBufferShort(short[][] 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 short arrays for the DataBuffer
.size
- The size of the banks in the DataBuffer
.public DataBufferShort(short[][] 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
.
