entryComparator
public static java.util.Comparator<? super java.util.Map.Entry<java.lang.Float,?>> entryComparator(FloatComparator comparator)
Returns a comparator for entries based on a given comparator on keys.- Parameters:
comparator
- a comparator on keys.- Returns:
- the associated comparator on entries.
