Constructor Details- 
DataBufferDoublepublic DataBufferDouble(int size) Constructs adouble-basedDataBufferwith a specified size.- Parameters:
- size- The number of elements in the- DataBuffer.
 
- 
DataBufferDoublepublic 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 the- DataBuffer.
- numBanks- The number of banks in the- DataBuffer.
 
- 
DataBufferDoublepublic 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 of- doubles to be used as the first and only bank of this- DataBuffer.
- size- The number of elements of the array to be used.
 
- 
DataBufferDoublepublic 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 of- doubles 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.
 
- 
DataBufferDoublepublic 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 of- doubles to be used as the banks of this- DataBuffer.
- size- The number of elements of each array to be used.
 
- 
DataBufferDoublepublic 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 of- doubles to be used as the banks of this- DataBuffer.
- size- The number of elements of each array to be used.
- offsets- An array of integer offsets, one for each bank.
