public final class DataBufferUShort
extends DataBuffer

This class extends DataBuffer and stores data internally as shorts. Values stored in the short array(s) of this DataBuffer are treated as unsigned values.

DataBufferUShort

public DataBufferUShort(int size)

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

Parameters:

size - The size of the DataBuffer.

DataBufferUShort

public DataBufferUShort(int size,
                        int numBanks)

Constructs an unsigned-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.

DataBufferUShort

public DataBufferUShort(short[] dataArray,
                        int size)

Constructs an unsigned-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 unsigned-short array for the DataBuffer.

size - The size of the DataBuffer bank.

DataBufferUShort

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

Constructs an unsigned-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 unsigned-short array for the DataBuffer.

size - The size of the DataBuffer bank.

offset - The offset into the dataArray.

DataBufferUShort

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

Constructs an unsigned-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 unsigned-short arrays for the DataBuffer.

size - The size of the banks in the DataBuffer.

DataBufferUShort

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

Constructs an unsigned-short based DataBuffer with 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 unsigned-short arrays for the DataBuffer.

size - The size of the banks in the DataBuffer.

offsets - The offsets into each array.

getBankData

public short[][] getBankData()

Returns the data arrays for all banks.

Returns:

All of the data arrays.

getData

public short[] getData()

Returns the default (first) unsigned-short data array.

Returns:

The first unsigned-short data array.

getData

public short[] getData(int bank)

Returns the data array for the specified bank.

Parameters:

bank - The bank whose data array you want to get.

Returns:

The data array for the specified bank.

getElem

public int getElem(int i)

Returns the requested data array element from the first (default) bank.

Overrides:

getElem in class DataBuffer

Parameters:

i - The data array element you want to get.

Returns:

The requested data array element as an integer.

getElem

public int getElem(int bank,
                   int i)

Returns the requested data array element from the specified bank.

Overrides:

getElem in class DataBuffer

Parameters:

bank - The bank from which you want to get a data array element.

i - The data array element you want to get.

Returns:

The requested data array element as an integer.

setElem

public void setElem(int i,
                    int val)

Sets the requested data array element in the first (default) bank to the specified value.

Overrides:

setElem in class DataBuffer

Parameters:

i - The data array element you want to set.

val - The integer value to which you want to set the data array element.

setElem

public void setElem(int bank,
                    int i,
                    int val)

Sets the requested data array element in the specified bank from the given integer.

Overrides:

setElem in class DataBuffer

Parameters:

bank - The bank in which you want to set the data array element.

i - The data array element you want to set.

val - The integer value to which you want to set the specified data array element.
