Constructor Detail

DataBufferByte

public DataBufferByte(int size)
Construct a byte based DataBuffer with specified size.

DataBufferByte

public DataBufferByte(int size,
                      int numBanks)
Construct a byte based DataBuffer with specified number of banks all of which are the specified size.

DataBufferByte

public DataBufferByte(byte[] dataArray,
                      int size)
Construct a byte based DataBuffer with the specified array. Only the first size elements are available for use by this databuffer. dataArray.length must be large enough to hold size elements.

DataBufferByte

public DataBufferByte(byte[] dataArray,
                      int size,
                      int offset)
Construct a byte based DataBuffer with the specified array, size, and offset. dataArray.length must be at least as large as offset + size.

DataBufferByte

public DataBufferByte(byte[][] dataArray,
                      int size)
Construct a byte based DataBuffer with specified 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.

DataBufferByte

public DataBufferByte(byte[][] dataArray,
                      int size,
                      int[] offsets)
Construct a byte based DataBuffer with specified arrays/size/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.
