with a specified size.
size
- The number of elements in the DataBuffer.public DataBufferFloat(int size, int numBanks)
float
-based DataBuffer
with a specified number of banks, all of which are of a
specified size.
size
- The number of elements in each bank of the
DataBuffer
.numBanks
- The number of banks in the
DataBuffer
.public DataBufferFloat(float[] dataArray, int size)
float
-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.

- An array of float
s to be used as the
first and only bank of this DataBuffer
.size
- The number of elements of the array to be used.public DataBufferFloat(float[] dataArray, int size, int offset)
float
-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.

with the specified data arrays. Only the first
size
elements of each array are available for use
by this DataBuffer
. The number of banks will be
equal to dataArray.length

float
-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.
