Method

voidswapBytesAt(byte[] bytes, int p1, int p2)
Swaps the bytes at the given positions. 
byte b = bytes[p1];
bytes[p1] = bytes[p2];
bytes[p2] = b;
voidswapElements(final E[] arr, final int idx1, final int idx2)
swap Elements 
final E temp = arr[idx1];
arr[idx1] = arr[idx2];
arr[idx2] = temp;
byte[]swapEndianFormat(byte[] b)
swap Endian Format 
byte[] endianSwappedBytes = new byte[b.length];
for (int i = 0; i < b.length; i++) {
    endianSwappedBytes[i] = swapEndianFormat(b[i]);
return endianSwappedBytes;
intswapInt(byte[] b, int i)
swap Int 
return Integer.reverseBytes(bytesToInt(b, i));
byte[]swapInts(byte b[], int off, int len)
swap Ints 
checkLength(len, 4);
for (int i = off, n = off + len; i < n; i += 4) {
    swap(b, i, i + 3);
    swap(b, i + 1, i + 2);
return b;
voidswapNumbers(int i, int j, double[] array)
swap Numbers 
double temp;
temp = array[i];
array[i] = array[j];
array[j] = temp;
voidswapObjects(Object[] array, int a, int b)
Swaps two Objects in an array of Objects. 
Object tmp = array[a]; 
array[a] = array[b]; 
array[b] = tmp;
voidswapOrder16(byte[] buffer, int byteOffset, int sampleCount)
swap Order 
int byteMax = sampleCount * 2 + byteOffset - 1;
int i = byteOffset;
while (i < byteMax) {
    byte h = buffer[i];
    buffer[i] = buffer[++i];
    buffer[i++] = h;
voidswapOrder32(byte[] buffer, int byteOffset, int sampleCount)
swap Order 
int byteMax = sampleCount * 4 + byteOffset - 3;
int i = byteOffset;
while (i < byteMax) {
    byte h = buffer[i];
    buffer[i] = buffer[i + 3];
    buffer[i + 3] = h;
    i++;
    h = buffer[i];
...
voidswapParallel(Object[] x, Object[] y, int a, int b, int yrel)
swap Parallel 
Object tx = x[a], ty = y[a + yrel];
x[a] = x[b];
y[a + yrel] = y[b + yrel];
x[b] = tx;
y[b + yrel] = ty;
