Class Reference2ObjectSortedMaps.EmptySortedMap<K,​V>

    • Method Detail

      • comparator

        public java.util.Comparator<? super K> comparator()
        Description copied from interface: Reference2ObjectSortedMap
        Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

        Note that this specification strengthens the one given in SortedMap.comparator().

        SortedMap.comparator()
      • entrySet

        public ObjectSortedSet<java.util.Map.Entry<K,​V>> entrySet()
        Returns a sorted-set view of the mappings contained in this map.

        Note that this specification strengthens the one given in the corresponding type-specific unsorted map.

        Specified by:
        entrySet in interface java.util.Map<K,​V>
        Specified by:
        entrySet in interface Reference2ObjectMap<K,​V>
        Specified by:
        entrySet in interface Reference2ObjectSortedMap<K,​V>
        Specified by:
        entrySet in interface java.util.SortedMap<K,​V>
        Returns:
        a sorted-set view of the mappings contained in this map.

      • subMap

        public Reference2ObjectSortedMap<K,​V> subMap​(K from,
                                                           K to)
        Description copied from interface: Reference2ObjectSortedMap
        Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

        Note that this specification strengthens the one given in SortedMap.subMap(Object,Object).

      • headMap

        public Reference2ObjectSortedMap<K,​V> headMap​(K to)
        Description copied from interface: Reference2ObjectSortedMap
        Returns a view of the portion of this sorted map whose keys are strictly less than toKey.

        Note that this specification strengthens the one given in SortedMap.headMap(Object).

        Description copied from interface: Reference2ObjectSortedMap
        Returns a view of the portion of this sorted map whose keys are greater than or equal to fromKey.

        Note that this specification strengthens the one given in SortedMap.tailMap(Object).
