Constructor Detail

DataBufferInt

public DataBufferInt(int size)
Construct an int based DataBuffer with specified size

DataBufferInt

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

DataBufferInt

public DataBufferInt(int[] dataArray,
                     int size)
Construct an int based DataBuffer with specified array. Only the first size elements are available for use by this databuffer. dataArray.length must be large enough to hold size elements.

DataBufferInt

public DataBufferInt(int[] dataArray,
                     int size,
                     int offset)
Construct an int based DataBuffer with specified array, size, and offset. dataArray.length must be at least as large as offset + size.

DataBufferInt

public DataBufferInt(int[][] dataArray,
                     int size)
Construct an int based DataBuffer with specified array. Only the first size elements are available for use by this databuffer. dataArray.length must be large enough to hold size elements.

DataBufferInt

public DataBufferInt(int[][] dataArray,
                     int size,
                     int[] offsets)
Construct an int 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.
