Method Detail

getComparator

public static Comparator<Object> getComparator()

getComparable

public static Comparable<Object> getComparable(Object o)

compare

public int compare(Object o1,
                   Object o2)

Specified by:

compare in interface Comparator<Object>

isIntegerType

public static boolean isIntegerType(Number n)

Determines if a particular number is an integer-type number such as Byte, Short, Integer, Long, AtomicInteger or AtomicLong. Note that BigInteger is not included in this set of number classes since treatment of BigInteger requires different logic.

Parameters:

n -

Returns:

toNumber

public static Number toNumber(Object value)
