Method Detail

naturalOrder

public static <T> SerializableComparator<T> naturalOrder()

Uses the natural compareTo methods of the objects which will throw if there are any nulls.

reverseNaturalOrder

public static <T> SerializableComparator<T> reverseNaturalOrder()

Uses the natural compareTo methods of the objects which will throw if there are any nulls.

reverse

public static <T> SerializableComparator<T> reverse(SerializableComparator<T> comparator)

Parameters:

comparator - original comparator whose order will be reversed

Returns:

A comparator that reverses the order of any other Serializable Comparator.

byFunction

public static <T,V extends Comparable<? super V>> SerializableComparator<T> byFunction(Function<? super T,? extends V> function)

byFunction

public static <T,V> SerializableComparator<T> byFunction(Function<? super T,? extends V> function,
