- 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. Note that DataBuffer
objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
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. Note that DataBuffer
objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
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
. Note that DataBuffer
objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
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. Note that DataBuffer
objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).

- An array of arrays of double
s to be used as the banks of this DataBuffer

- The number of elements of each array to be used.offsets
- An array of integer offsets, one for each bank.public double[] getData()
