public DataBufferDouble(int size)
double
-based DataBuffer
with a specified size.
size
- The number of elements in the DataBuffer
.public DataBufferDouble(int size, int numBanks)
double
-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 DataBufferDouble(double[] dataArray, int size)
double
-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.
dataArray
- An array of double
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 DataBufferDouble(double[] dataArray, int size, int offset)
double
-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.
dataArray
- An array of double
s to be used as the
first and only bank of this DataBuffer
.size
- The number of elements of the array to be used.offset
- The offset of the first element of the array
that will be used.public DataBufferDouble(double[][] dataArray, int size)
double
-based DataBuffer
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
.
dataArray
- An array of arrays of double
s to be
used as the banks of this DataBuffer
.size
- The number of elements of each array to be used.public DataBufferDouble(double[][] dataArray, int size, int[] offsets)
double
-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.
