Method Detail

comparator

public Comparator<? super K> comparator()

Description copied from interface: Object2LongSortedMap

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 Object2LongSortedMap<K>

Specified by:

comparator in interface SortedMap<K,Long>

See Also:

SortedMap.comparator()

object2LongEntrySet

public ObjectSortedSet<Object2LongMap.Entry<K>> object2LongEntrySet()

Description copied from interface: Object2LongMap

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

This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Object2LongMap.entrySet() so that it returns an ObjectSet of objects of type Map.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

object2LongEntrySet in interface Object2LongMap<K>

Specified by:

object2LongEntrySet in interface Object2LongSortedMap<K>

Overrides:

object2LongEntrySet in class Object2LongMaps.EmptyMap<K>

Returns:

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

See Also:

Object2LongMap.entrySet()

entrySet

public ObjectSortedSet<Map.Entry<K,Long>> entrySet()

Description copied from interface: Object2LongMap

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

Note that this specification strengthens the one given in Map.entrySet().

Specified by:

entrySet in interface Object2LongMap<K>

Specified by:

entrySet in interface Object2LongSortedMap<K>

Specified by:

entrySet in interface Map<K,Long>

Specified by:

entrySet in interface SortedMap<K,Long>

Overrides:

entrySet in class Object2LongMaps.EmptyMap<K>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public ObjectSortedSet<K> keySet()

Description copied from interface: Object2LongMap

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

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface Object2LongMap<K>

Specified by:

keySet in interface Object2LongSortedMap<K>

Specified by:

keySet in interface Map<K,Long>

Specified by:

keySet in interface SortedMap<K,Long>

Overrides:

keySet in class Object2LongMaps.EmptyMap<K>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Object2LongSortedMap<K> subMap(K from,
                             K to)

Description copied from interface: Object2LongSortedMap

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 Object2LongSortedMap<K>

Specified by:

subMap in interface SortedMap<K,Long>

See Also:

SortedMap.subMap(Object,Object)

headMap

public Object2LongSortedMap<K> headMap(K to)

Description copied from interface: Object2LongSortedMap

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 Object2LongSortedMap<K>

Specified by:

headMap in interface SortedMap<K,Long>

See Also:

SortedMap.headMap(Object)

tailMap

public Object2LongSortedMap<K> tailMap(K from)

Description copied from interface: Object2LongSortedMap

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 Object2LongSortedMap<K>

Specified by:

tailMap in interface SortedMap<K,Long>
