Interface Reference2LongSortedMap<K>

All Superinterfaces:

Function<K,Long>, Map<K,Long>, Reference2LongFunction<K>, Reference2LongMap<K>, SortedMap<K,Long>

All Known Implementing Classes:

AbstractReference2LongSortedMap, Reference2LongLinkedOpenHashMap, Reference2LongSortedMaps.EmptySortedMap, Reference2LongSortedMaps.Singleton, Reference2LongSortedMaps.SynchronizedSortedMap, Reference2LongSortedMaps.UnmodifiableSortedMap

public interface Reference2LongSortedMap<K>
extends Reference2LongMap<K>, SortedMap<K,Long>

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 Detail

entrySet

ObjectSortedSet<Map.Entry<K,Long>> 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 Map<K,Long>

Specified by:

entrySet in interface Reference2LongMap<K>

Specified by:

entrySet in interface SortedMap<K,Long>

Returns:

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

See Also:

Map.entrySet()

reference2LongEntrySet

ObjectSortedSet<Reference2LongMap.Entry<K>> reference2LongEntrySet()

Returns a type-specific 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:

reference2LongEntrySet in interface Reference2LongMap<K>

Returns:

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

See Also:

entrySet()

keySet

ReferenceSortedSet<K> keySet()

Returns a sorted-set view of the keys contained in this map. Note that this specification strengthens the one given in the corresponding type-specific unsorted map.

Specified by:

keySet in interface Map<K,Long>

Specified by:

keySet in interface Reference2LongMap<K>

Specified by:

keySet in interface SortedMap<K,Long>

Returns:

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

See Also:

Map.keySet()

values

LongCollection values()

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

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.

Specified by:

values in interface Map<K,Long>

Specified by:

values in interface Reference2LongMap<K>

Specified by:

values in interface SortedMap<K,Long>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

comparator

Comparator<? super K> comparator()

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().

Specified by:

comparator in interface SortedMap<K,Long>

See Also:

SortedMap.comparator()

subMap

Reference2LongSortedMap<K> subMap(K fromKey,
                                K toKey)

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).

Specified by:

subMap in interface SortedMap<K,Long>

See Also:

SortedMap.subMap(Object,Object)

headMap

Reference2LongSortedMap<K> headMap(K toKey)

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).

Specified by:

headMap in interface SortedMap<K,Long>

See Also:

SortedMap.headMap(Object)

tailMap

Reference2LongSortedMap<K> tailMap(K fromKey)

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).

Specified by:

tailMap in interface SortedMap<K,Long>

See Also:

SortedMap.tailMap(Object)
