public static <K> ReferenceSortedSet<K> singleton(K element)
element
- the only element of the returned sorted set.
element
.public static <K> ReferenceSortedSet<K> singleton(K element, Comparator<? super K> comparator)
element
- the only element of the returned sorted set.comparator
- the comparator to use in the returned sorted set.
element
.public static <K> ReferenceSortedSet<K> synchronize(ReferenceSortedSet<K> s)
s
- the sorted set to be wrapped in a synchronized sorted set.
Collections.synchronizedSortedSet(SortedSet)
public static <K> ReferenceSortedSet<K> synchronize(ReferenceSortedSet<K> s, Object sync)
s
- the sorted set to be wrapped in a synchronized sorted set.sync
- an object that will be used to synchronize the access to the sorted set.
