Interface Reference2ReferenceSortedMap<K,V>

All Superinterfaces:

Function<K,V>, Function<K,V>, Map<K,V>, Reference2ReferenceFunction<K,V>, Reference2ReferenceMap<K,V>, SequencedMap<K,V>, SortedMap<K,V>

All Known Implementing Classes:

AbstractReference2ReferenceSortedMap, Reference2ReferenceLinkedOpenHashMap, Reference2ReferenceSortedMaps.EmptySortedMap, Reference2ReferenceSortedMaps.Singleton, Reference2ReferenceSortedMaps.SynchronizedSortedMap, Reference2ReferenceSortedMaps.UnmodifiableSortedMap

public interface Reference2ReferenceSortedMap<K,V>
extends Reference2ReferenceMap<K,V>, 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

Reference2ReferenceSortedMap<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 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

Reference2ReferenceSortedMap<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 SortedMap<K,V>

See Also:

• SortedMap.headMap(Object)

API Notes:

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

tailMap

Reference2ReferenceSortedMap<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 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<Map.Entry<K,V>> entrySet()

Returns a sorted-set view of the mappings contained in this map.

Specified by:

entrySet in interface Map<K,V>

Specified by:

entrySet in interface Reference2ReferenceMap<K,V>

Specified by:

entrySet in interface 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.

reference2ReferenceEntrySet

ObjectSortedSet<Reference2ReferenceMap.Entry<K,V>> reference2ReferenceEntrySet()

Returns a type-specific sorted-set view of the mappings contained in this map.

Specified by:

reference2ReferenceEntrySet in interface Reference2ReferenceMap<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

ReferenceSortedSet<K> keySet()

Returns a type-specific sorted-set view of the keys contained in this map.

Specified by:

keySet in interface Map<K,V>

Specified by:

keySet in interface Reference2ReferenceMap<K,V>

Specified by:

keySet in interface 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

ReferenceCollection<V> values()

Returns a type-specific set view of the values contained in this map.

Specified by:

values in interface Map<K,V>

Specified by:

values in interface Reference2ReferenceMap<K,V>

Specified by:

values in interface 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

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 SortedMap<K,V>

See Also:

• SortedMap.comparator()

API Notes:

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