public static class Reference2ReferenceSortedMaps.Singleton<K,V> extends Reference2ReferenceMaps.Singleton<K,V> implements Reference2ReferenceSortedMap<K,V>, java.io.Serializable, java.lang.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 java.util.Comparator<? super K> comparator()
Description copied from interface:Reference2ReferenceSortedMap
Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.- Specified by:
comparator
in interfaceReference2ReferenceSortedMap<K,V>
- Specified by:

in interfacejava.util.SortedMap<K,V>
- See Also:
SortedMap.comparator()
-
reference2ReferenceEntrySet
public ObjectSortedSet<Reference2ReferenceMap.Entry<K,V>> reference2ReferenceEntrySet()
Description copied from interface:Reference2ReferenceMap
Returns a type-specific set view of the mappings contained in this map.This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen
Map.entrySet()
so that it returns anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
reference2ReferenceEntrySet
in interfaceReference2ReferenceMap<K,V>
- Specified by:
reference2ReferenceEntrySet
in interfaceReference2ReferenceSortedMap<K,V>
- Overrides:
reference2ReferenceEntrySet
in classReference2ReferenceMaps.Singleton<K,V>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
public ObjectSortedSet<java.util.Map.Entry<K,V>> entrySet()
Returns a set view of the mappings contained in this map.- Specified by:
