Method Details

comparator

public LongComparator comparator()

Description copied from interface: Long2ReferenceSortedMap

Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

Specified by:

comparator in interface Long2ReferenceSortedMap<V>

Specified by:

comparator in interface SortedMap<Long,V>

See Also:

• SortedMap.comparator()

long2ReferenceEntrySet

public ObjectSortedSet<Long2ReferenceMap.Entry<V>> long2ReferenceEntrySet()

Description copied from interface: Long2ReferenceMap

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

Specified by:

long2ReferenceEntrySet in interface Long2ReferenceMap<V>

Specified by:

long2ReferenceEntrySet in interface Long2ReferenceSortedMap<V>

Overrides:

long2ReferenceEntrySet in class Long2ReferenceMaps.EmptyMap<V>

Returns:

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

See Also:

• Map.entrySet()

entrySet

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

Deprecated.

Please use the corresponding type-specific method instead.

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

Specified by:

entrySet in interface Long2ReferenceMap<V>

Specified by:

entrySet in interface Long2ReferenceSortedMap<V>

Specified by:

entrySet in interface Map<Long,V>

Specified by:

entrySet in interface SortedMap<Long,V>

Returns:

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

keySet

public LongSortedSet keySet()

Description copied from interface: Long2ReferenceMap

Specified by:

Specified by:

keySet in interface Map<Long,V>

Specified by:

keySet in interface SortedMap<Long,V>

Overrides:

keySet in class Long2ReferenceMaps.EmptyMap<V>

a set view of the keys contained in this map.

See Also:

• Map.keySet()

subMap

public Long2ReferenceSortedMap<V> subMap(long from,
