DataBufferDouble
public DataBufferDouble(int size)
Constructs adouble-basedDataBufferwith a specified size.- Parameters:
size- The number of elements in theDataBuffer.
-
DataBufferDouble
public DataBufferDouble(int size, int numBanks)Constructs adouble-basedDataBufferwith a specified number of banks, all of which are of a specified size.- Parameters:
size- The number of elements in each bank of theDataBuffer.numBanks- The number of banks in theDataBuffer.
-
DataBufferDouble
public DataBufferDouble(double[] dataArray, int size)Constructs adouble-basedDataBufferwith the specified data array. Only the firstsizeelements are available for use by thisDataBuffer. The array must be large enough to holdsizeelements.Note that
DataBufferobjects 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 ofdoubles 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-basedDataBufferwith the specified data array. Only the elements betweenoffsetandoffset + size - 1are available for use by thisDataBuffer. The array must be large enough to holdoffset + sizeelements.Note that
DataBufferobjects 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 ofdoubles 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-basedDataBufferwith the specified data arrays. Only the firstsizeelements of each array are available for use by thisDataBuffer. The number of banks will be equalto dataArray.length.Note that
DataBufferobjects 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 ofdoubles to be used as the banks of thisDataBuffer.size- The number of elements of each array to be used.
-
DataBufferDouble
public DataBufferDouble(double[][] dataArray, int size, int[] offsets)Constructs adouble-basedDataBufferwith 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 assizeplus the corresponding offset. There must be an entry in theoffsetsarray for each data array.Note that
DataBufferobjects 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 ofdoubles 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.
