public static class Reference2ObjectSortedMaps.Singleton
extends Reference2ObjectMaps.Singleton
implements Reference2ObjectSortedMap, Serializable, Cloneable

An immutable class representing a type-specific singleton sorted map.

This class may be useful to implement your own in case you subclass a type-specific sorted map.

Method Detail

comparator

public Comparator comparator()
Specified by:
comparator in interface SortedMap

keySet

public Set keySet()
Description copied from class: AbstractReference2ObjectMap
Returns a type-specific-set view of the keys of this map.

The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:
keySet in interface Map
