Method Details

comparator

public Comparator<? super K> comparator()

Description copied from interface: Reference2IntSortedMap

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

Specified by:

comparator in interface Reference2IntSortedMap<K>

Specified by:

comparator in interface SortedMap<K,Integer>

See Also:

• SortedMap.comparator()

reference2IntEntrySet

public ObjectSortedSet<Reference2IntMap.Entry<K>> reference2IntEntrySet()

Description copied from interface: Reference2IntMap

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:

reference2IntEntrySet in interface Reference2IntMap<K>

Specified by:

reference2IntEntrySet in interface Reference2IntSortedMap<K>

Overrides:

reference2IntEntrySet in class Reference2IntMaps.Singleton<K>

Returns:

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

See Also:

• Map.entrySet()

entrySet

@Deprecated
public ObjectSortedSet<Map.Entry<K,Integer>> entrySet()

Deprecated.

Please use the corresponding type-specific method instead.

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

Specified by:

entrySet in interface Map<K,Integer>

Specified by:

entrySet in interface Reference2IntMap<K>

Specified by:

entrySet in interface Reference2IntSortedMap<K>

Specified by:

entrySet in interface SortedMap<K,Integer>

Overrides:

entrySet in class Reference2IntMaps.Singleton<K>

Returns:

a set view of the mappings contained in this map.

See Also:

• Map.entrySet()

keySet

public ReferenceSortedSet<K> keySet()

Description copied from interface: Reference2IntMap

Specified by:

keySet in interface Map<K,Integer>

Specified by:

keySet in interface Reference2IntMap<K>

Specified by:

keySet in interface Reference2IntSortedMap<K>

Specified by:

keySet in interface SortedMap<K,Integer>

Overrides:

keySet in class Reference2IntMaps.Singleton<K>

Returns:

a set view of the keys contained in this map.

See Also:

• Map.keySet()

subMap

public Reference2IntSortedMap<K> subMap(K from,
 K to)

Description copied from interface: Reference2IntSortedMap

• SortedMap.subMap(Object,Object)

headMap

public Reference2IntSortedMap<K> headMap(K to)

Description copied from interface: Reference2IntSortedMap
