data
protected byte[] data
- The default data bank.
bankdata
protected byte[][] bankdata
- All data banks
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.
getData
public byte[] getData()
- Return the default (first) byte data array
getData
public byte[] getData(int bank)
- Return the data array for the specified bank
getBankData
public byte[][] getBankData()
- Return the data array for all banks
getElem
public int getElem(int i)

as an integer.
- Overrides:
- getElem in class DataBuffer
getElem

int i)
- Returns the requested data array element from the specified bank
as an integer.
- Overrides:

int val)
- Sets the requested data array element in the first (default) bank
from the given integer.
- Overrides:
- setElem in class DataBuffer
setElem
