Method Detail

comparator

public LongComparator comparator()

Description copied from interface: Long2ObjectSortedMap

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 Long2ObjectSortedMap<V>

Specified by:

comparator in interface SortedMap<Long,V>

See Also:

SortedMap.comparator()

long2ObjectEntrySet

public ObjectSortedSet<Long2ObjectMap.Entry<V>> long2ObjectEntrySet()

Description copied from interface: Long2ObjectMap

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 Long2ObjectMap.entrySet() so that it returns an ObjectSet of objects of type Long2ObjectMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

long2ObjectEntrySet in interface Long2ObjectMap<V>

Specified by:

long2ObjectEntrySet in interface Long2ObjectSortedMap<V>

Overrides:

long2ObjectEntrySet in class Long2ObjectMaps.EmptyMap<V>

Returns:

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

See Also:

Long2ObjectMap.entrySet()

entrySet

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

Description copied from interface: Long2ObjectMap

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 Long2ObjectMap<V>

Specified by:

entrySet in interface Long2ObjectSortedMap<V>

Specified by:

entrySet in interface Map<Long,V>

Overrides:

entrySet in class Long2ObjectMaps.EmptyMap<V>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public LongSortedSet keySet()

Description copied from interface: Long2ObjectMap

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 Long2ObjectMap<V>

Specified by:

keySet in interface Long2ObjectSortedMap<V>

Specified by:

keySet in interface Map<Long,V>

Overrides:

keySet in class Long2ObjectMaps.EmptyMap<V>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap
