All Superinterfaces:
Function<K,​V>, java.util.function.Function<K,​V>, java.util.Map<K,​V>, Object2ReferenceFunction<K,​V>, Object2ReferenceMap<K,​V>, java.util.SortedMap<K,​V>
All Known Implementing Classes:
AbstractObject2ReferenceSortedMap, Object2ReferenceAVLTreeMap, Object2ReferenceLinkedOpenCustomHashMap, Object2ReferenceLinkedOpenHashMap, Object2ReferenceRBTreeMap, Object2ReferenceSortedMaps.EmptySortedMap, Object2ReferenceSortedMaps.Singleton, Object2ReferenceSortedMaps.SynchronizedSortedMap, Object2ReferenceSortedMaps.UnmodifiableSortedMap

public interface Object2ReferenceSortedMap<K,​V>
extends Object2ReferenceMap<K,​V>, java.util.SortedMap<K,​V>
A type-specific SortedMap; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens entrySet(), keySet(), values(), comparator(), SortedMap.subMap(Object,Object), SortedMap.headMap(Object) and SortedMap.tailMap(Object).

  • Method Details

    • subMap

      Object2ReferenceSortedMap<K,​V> subMap​(K fromKey, K toKey)
      Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.
      Specified by:
      subMap in interface java.util.SortedMap<K,​V>
      See Also:
      SortedMap.subMap(Object,Object)
      API Notes:
      Note that this specification strengthens the one given in SortedMap.subMap(Object,Object).
    • headMap

      Object2ReferenceSortedMap<K,​V> headMap​(K toKey)
      Returns a view of the portion of this sorted map whose keys are strictly less than toKey.
      Specified by:
      headMap in interface java.util.SortedMap<K,​V>
      See Also:
      SortedMap.headMap(Object)
      API Notes:
      Note that this specification strengthens the one given in SortedMap.headMap(Object).
    • tailMap

      Object2ReferenceSortedMap<K,​V> tailMap​(K fromKey)
      Returns a view of the portion of this sorted map whose keys are greater than or equal to fromKey.
      Specified by:
      tailMap in interface java.util.SortedMap<K,​V>
      See Also:
      SortedMap.tailMap(Object)
      API Notes:
      Note that this specification strengthens the one given in SortedMap.tailMap(Object).
    • entrySet

      default ObjectSortedSet<java.util.Map.Entry<K,​V>> entrySet()
      Returns a sorted-set view of the mappings contained in this map.
      Specified by:
      entrySet in interface java.util.Map<K,​V>
      Specified by:
      entrySet in interface Object2ReferenceMap<K,​V>
      Specified by:
      entrySet in interface java.util.SortedMap<K,​V>
      Returns:
      a sorted-set view of the mappings contained in this map.
      See Also:
      Map.entrySet()
      API Notes:
      Note that this specification strengthens the one given in the corresponding type-specific unsorted map.
    • object2ReferenceEntrySet

      ObjectSortedSet<Object2ReferenceMap.Entry<K,​V>> object2ReferenceEntrySet()
      Returns a type-specific sorted-set view of the mappings contained in this map.
      Specified by:
      object2ReferenceEntrySet in interface Object2ReferenceMap<K,​V>
      Returns:
      a type-specific sorted-set view of the mappings contained in this map.
      See Also:
      entrySet()
      API Notes:
      Note that this specification strengthens the one given in the corresponding type-specific unsorted map.
    • keySet

      ObjectSortedSet<K> keySet()
      Returns a type-specific sorted-set view of the keys contained in this map.
      Specified by:
      keySet in interface java.util.Map<K,​V>
      Specified by:
      keySet in interface Object2ReferenceMap<K,​V>
      Specified by:
      keySet in interface java.util.SortedMap<K,​V>
      Returns:
      a sorted-set view of the keys contained in this map.
      See Also:
      SortedMap.keySet()
      API Notes:
      Note that this specification strengthens the one given in the corresponding type-specific unsorted map.
    • values

      Returns a type-specific set view of the values contained in this map.
      Specified by:
      values in interface java.util.Map<K,​V>
      Specified by:
      values in interface Object2ReferenceMap<K,​V>
      Specified by:
      values in interface java.util.SortedMap<K,​V>
      Returns:
      a set view of the values contained in this map.
      See Also:
      SortedMap.values()
      API Notes:
      Note that this specification strengthens the one given in Map.values(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends SortedMap.
    • comparator

      java.util.Comparator<? super K> comparator()
      Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
      Specified by:
      comparator in interface java.util.SortedMap<K,​V>
      See Also:
      SortedMap.comparator()
      API Notes:
      Note that this specification strengthens the one given in SortedMap.comparator().
