- Method Detail
  - getUnsignedInt
```
public static @Unsigned int getUnsignedInt(ByteBuffer b)
```
    Gets an unsigned int from the ByteBuffer b. Wraps getInt(), but assumes that the result should be interpreted as unsigned.
  - getUnsignedShort
```
public static @Unsigned short getUnsignedShort(ByteBuffer b)
```
    Gets an unsigned short from the ByteBuffer b. Wraps getShort(), but assumes that the result should be interpreted as unsigned.
  - getUnsigned
```
public static @Unsigned byte getUnsigned(ByteBuffer b)
```
    Gets an unsigned byte from the ByteBuffer b. Wraps get(), but assumes that the result should be interpreted as unsigned.
  - getUnsigned
```
public static void getUnsigned(ByteBuffer b,
                               @Unsigned byte[] bs)
```
    Gets an array of unsigned bytes from the ByteBuffer b and stores them in the array bs. Wraps get(byte[]), but assumes that the array of bytes should be interpreted as unsigned.
  - compareUnsigned
```
public static int compareUnsigned(@Unsigned long x,
                                  @Unsigned long y)
```
    Compares two unsigned longs x and y.
    This is a reimplementation of Java 8's Long.compareUnsigned(long, long).
    
    Returns:
    
    a negative number iff x < y, a positive number iff x > y, and zero iff x == y.
  - compareUnsigned
```
public static int compareUnsigned(@Unsigned int x,
                                  @Unsigned int y)
```
    Compares two unsigned ints x and y.
    This is a reimplementation of Java 8's Integer.compareUnsigned(int, int).
    
    Returns:
    
    a negative number iff x < y, a positive number iff x > y, and zero iff x == y.
  - compareUnsigned
```
public static int compareUnsigned(@Unsigned short x,
                                  @Unsigned short y)
```
    Compares two unsigned shorts x and y.
    
    Returns:
    
    a negative number iff x < y, a positive number iff x > y, and zero iff x == y.
