Constructor Detail

DataBufferShort

public DataBufferShort(int size)

Constructs a short-based DataBuffer with a single bank and the specified size.

Parameters:

size - The size of the DataBuffer.

DataBufferShort

public DataBufferShort(int size,
                       int numBanks)

Constructs a short-based DataBuffer with the specified number of banks all of which are the specified size.

Parameters:

size - The size of the banks in the DataBuffer.

numBanks - The number of banks in the aDataBuffer.

DataBufferShort

public DataBufferShort(short[] dataArray,
                       int size)

Constructs a short-based DataBuffer with a single bank using the specified array. Only the first size elements should be used by accessors of this DataBuffer. dataArray must be large enough to hold size elements.

Parameters:

dataArray - The short array for the DataBuffer.

size - The size of the DataBuffer bank.

DataBufferShort

public DataBufferShort(short[] dataArray,
                       int size,
                       int offset)

Constructs a short-based DataBuffer with a single bank using the specified array, size, and offset. dataArray must have at least offset + size elements. Only elements offset through offset + size - 1 should be used by accessors of this DataBuffer.

Parameters:

dataArray - The short array for the DataBuffer.

size - The size of the DataBuffer bank.

offset - The offset into the dataArray.

DataBufferShort

public DataBufferShort(short[][] dataArray,
                       int size)

Constructs a short-based DataBuffer with the specified arrays. The number of banks will be equal to dataArray.length. Only the first size elements of each array should be used by accessors of this DataBuffer.

Parameters:

dataArray - The short arrays for the DataBuffer.

size - The size of the banks in the DataBuffer.

DataBufferShort

public DataBufferShort(short[][] dataArray,
                       int size,
                       int[] offsets)

Constructs a short-based DataBuffer with the specified arrays, size, and offsets. The number of banks is equal to dataArray.length. Each array must be at least as large as size + the corresponding offset. There must be an entry in the offset array for each dataArray entry. For each bank, only elements offset through offset + size - 1 should be used by accessors of this DataBuffer.

Parameters:

dataArray - The short arrays for the DataBuffer.

size - The size of the banks in the DataBuffer.

offsets - The offsets into each array.
