Public Methods
public static int compareUnsigned (long x, long y)
Compare two longs as unsigned.
public static long divUnsigned (long dividend, long divisor)
Divide two longs treated as unsigned.
public static boolean equals (Long a, long b)
Safe equality.
Parameters
| a | may be null |
|---|
Returns
- true if a is not null and its long value equal to b
public static boolean equals (Long a, Long b)
Safe equality.
Parameters
| a | may be null |
|---|---|
| b | may be null |
Returns
- true if both a and b are null or if their long values are equal
public static boolean equals (long a, Long b)
Safe equality.
Parameters
| b | may be null |
|---|
Returns
- true if b is not null and its long value equal to a
