Interface Long2LongSortedMap

All Superinterfaces:

Function<Long,Long>, Long2LongFunction, Long2LongMap, Map<Long,Long>, SortedMap<Long,Long>

All Known Implementing Classes:

AbstractLong2LongSortedMap, Long2LongAVLTreeMap, Long2LongLinkedOpenHashMap, Long2LongRBTreeMap, Long2LongSortedMaps.EmptySortedMap, Long2LongSortedMaps.Singleton, Long2LongSortedMaps.SynchronizedSortedMap, Long2LongSortedMaps.UnmodifiableSortedMap

public interface Long2LongSortedMap
extends Long2LongMap, SortedMap<Long,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<Long,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 Long2LongMap

Specified by:

entrySet in interface Map<Long,Long>

Specified by:

entrySet in interface SortedMap<Long,Long>

Returns:

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

See Also:

Map.entrySet()

long2LongEntrySet

ObjectSortedSet<Long2LongMap.Entry> long2LongEntrySet()

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:

long2LongEntrySet in interface Long2LongMap

Returns:

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

See Also:

entrySet()

keySet

LongSortedSet 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 Long2LongMap

Specified by:

keySet in interface Map<Long,Long>

Specified by:

keySet in interface SortedMap<Long,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 Long2LongMap

Specified by:

values in interface Map<Long,Long>

Specified by:

values in interface SortedMap<Long,Long>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

comparator

LongComparator 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<Long,Long>

See Also:

SortedMap.comparator()

subMap

Long2LongSortedMap subMap(Long fromKey,
                        Long 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<Long,Long>

See Also:

SortedMap.subMap(Object,Object)

headMap

Long2LongSortedMap headMap(Long 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).

See Also:

SortedMap.headMap(Object)

tailMap

Long2LongSortedMap tailMap(Long 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<Long,Long>

See Also:

SortedMap.tailMap(Object)

subMap

Long2LongSortedMap subMap(long fromKey,
                        long toKey)
