Method Detail

inverse

public static <T> Comparator<T> inverse(Comparator<T> baseComp)

This is a "reverse" comparator. Positive becomes negative, negative becomes positive and 0 (equal) stays the same. This was poorly named as "inverse" as it's not really inverting a true/false relationship

Type Parameters:

T -

Parameters:

baseComp -

Returns:

comparable

@Deprecated
public static <T extends Comparable> Comparator<T> comparable()

Use Guava Ordering.natural() instead

Type Parameters:

T -

Returns:

intervals

@Deprecated
public static Comparator<org.joda.time.Interval> intervals()

Deprecated.
