Constructor Detail

DataBufferDouble

public DataBufferDouble(int size)
Constructs a double-based DataBuffer with a specified size.

Parameters:
size - The number of elements in the DataBuffer.

DataBufferDouble

public DataBufferDouble(int size,
                        int numBanks)
Constructs a double-based DataBuffer with 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.

DataBufferDouble

public DataBufferDouble(double[] dataArray,
                        int size)
Constructs a 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.

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.

DataBufferDouble

public DataBufferDouble(double[] dataArray,
                        int size,
                        int offset)
Constructs a 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.

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.

DataBufferDouble

public DataBufferDouble(double[][] dataArray,
                        int size)
Constructs a 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.

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.

DataBufferDouble

public DataBufferDouble(double[][] dataArray,
                        int size,
                        int[] offsets)
Constructs a 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.

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.
