Constructor Detail

DataBufferShort

public DataBufferShort(int size)
Construct a short based DataBuffer with specified size.

DataBufferShort

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

DataBufferShort

public DataBufferShort(short[] dataArray,
                       int size)
Construct a short 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.

DataBufferShort

public DataBufferShort(short[] dataArray,
                       int size,
                       int offset)
Construct a short 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.

DataBufferShort

public DataBufferShort(short[][] dataArray,
                       int size)
Construct a short based DataBuffer with the 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.

DataBufferShort

public DataBufferShort(short[][] dataArray,
                       int size,
                       int[] offsets)
Construct a short 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.
Method Detail

getData

public short[] getData()
