DataBufferUShort

public final class DataBufferUShort extends DataBuffer
The Class DataBufferUShort is the subclass of DataBuffer for the case where the underlying data is unsigned short.
since
Android 1.0

Fields Summary
short[]
data
The data.
Constructors Summary
public DataBufferUShort(short[] dataArrays, int size, int[] offsets)
Instantiates a new data buffer of type unsigned short.

param
dataArrays the data arrays to copy the data from.
param
size the length (number of elements) to use from the data arrays.
param
offsets the starting indices for reading the data from the internal data arrays.

public DataBufferUShort(short[] dataArrays, int size)
Instantiates a new data buffer of type unsigned short.

param

        data = dataArrays.clone();
public DataBufferUShort(short[] dataArray, int size, int offset)
Instantiates a new data buffer of type unsigned short with a single underlying array of data.

param
dataArray the data array to copy the data from.

public DataBufferUShort(short[] dataArray, int size)
Instantiates a new data buffer of type unsigned short with a single underlying array of data starting at index 0.

public DataBufferUShort(int size, int numBanks)
Instantiates a new empty data buffer of type unsigned short with offsets equal to zero.

param

        }
public DataBufferUShort(int size)
