DataBufferDouble
public DataBufferDouble(double[] dataArray, int size)
Constructs adouble
-basedDataBuffer
with the specified data array. Only the firstsize
elements are available for use by thisDataBuffer
. The array must be large enough to holdsize
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).- Parameters:
dataArray
- An array ofdouble
s to be used as the first and only bank of thisDataBuffer
.size
- The number of elements of the array to be used.
-
DataBufferDouble
public DataBufferDouble(double[] dataArray, int size, int offset)
Constructs adouble
-basedDataBuffer
with the specified data array. Only the elements betweenoffset
andoffset + size - 1
are available for use by thisDataBuffer
. The array must be large enough to holdoffset + 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).- Parameters:
dataArray
- An array ofdouble
s to be used as the first and only bank of thisDataBuffer
.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.
-
DataBufferDouble
public DataBufferDouble(double[][] dataArray, int size)
Constructs adouble
-basedDataBuffer
with the specified data arrays. Only the firstsize
elements of each array are available for use by thisDataBuffer
. The number of banks will be equalto 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).- Parameters:
dataArray

-
DataBufferDouble
public DataBufferDouble(double[][] dataArray, int size, int[] offsets)
Constructs adouble
-basedDataBuffer
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 assize
plus the corresponding offset. There must be an entry in theoffsets
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).- Parameters:
dataArray
- An array of arrays ofdouble
s to be used as the banks of thisDataBuffer
.size
- The number of elements of each array to be used.offsets
- An array of integer offsets, one for each bank.
