public final class DataBufferByte extends DataBuffer
This class extends DataBuffer and stores data internally as bytes. Values stored in the byte array(s) of this DataBuffer are treated as unsigned values.
banks, dataType, offset, offsets, size, TYPE_BYTE, TYPE_DOUBLE, TYPE_FLOAT, TYPE_INT, TYPE_SHORT, TYPE_UNDEFINED, TYPE_USHORT public DataBufferByte(int size)
Constructs a byte-based DataBuffer with a single bank and the specified size.
size - The size of the DataBuffer.public DataBufferByte(int size,
int numBanks) Constructs a byte based DataBuffer with the specified number of banks all of which are the specified size.
size - The size of the banks in the DataBuffer.numBanks - The number of banks in the aDataBuffer.public DataBufferByte(byte[] dataArray,
int size) Constructs a byte-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.
Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
dataArray - The byte array for the DataBuffer.size - The size of the DataBuffer bank.public DataBufferByte(byte[] dataArray,
int size,
int offset) Constructs a byte-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.
Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
dataArray - The byte array for the DataBuffer.size - The size of the DataBuffer bank.offset - The offset into the dataArray. dataArray must have at least offset + size elements.public DataBufferByte(byte[][] dataArray,
int size) Constructs a byte-based DataBuffer with the specified arrays. The number of banks is equal to dataArray.length. Only the first size elements of each array should be used by accessors of this DataBuffer.
Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
dataArray - The byte arrays for the DataBuffer.size - The size of the banks in the DataBuffer.public DataBufferByte(byte[][] dataArray,
int size,
int[] offsets) Constructs a byte-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.
Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
dataArray - The byte arrays for the DataBuffer.size - The size of the banks in the DataBuffer.offsets - The offsets into each array.public byte[] getData()
Returns the default (first) byte data array.
Note that calling this method may cause this DataBuffer object to be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
public byte[] getData(int bank)
Returns the data array for the specified bank.
Note that calling this method may cause this DataBuffer object to be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
bank - The bank whose data array you want to get.public byte[][] getBankData()
Returns the data arrays for all banks.
Note that calling this method may cause this DataBuffer object to be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
public int getElem(int i)
Returns the requested data array element from the first (default) bank.

i - The data array element you want to get.setElem(int, int), setElem(int, int, int)
public int getElem(int bank,
int i) Returns the requested data array element from the specified bank.

bank - The bank from which you want to get a data array element.i - The data array element you want to get.setElem(int, int), setElem(int, int, int)
public void setElem(int i,
int val) Sets the requested data array element in the first (default) bank to the specified value.

i - The data array element you want to set.val - The integer value to which you want to set the data array element.getElem(int), getElem(int, int)
public void setElem(int bank,
int i,
int val) Sets the requested data array element in the specified bank from the given integer.
