Method Details

comparator

public Comparator<? super K> comparator()

Description copied from interface: Object2ReferenceSortedMap

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

Specified by:

comparator in interface Object2ReferenceSortedMap<K,V>

Specified by:

comparator in interface SortedMap<K,V>

See Also:

• SortedMap.comparator()

object2ReferenceEntrySet

public ObjectSortedSet<Object2ReferenceMap.Entry<K,V>> object2ReferenceEntrySet()

Description copied from interface: Object2ReferenceMap

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:

object2ReferenceEntrySet in interface Object2ReferenceMap<K,V>

Specified by:

object2ReferenceEntrySet in interface Object2ReferenceSortedMap<K,V>

Overrides:

object2ReferenceEntrySet in class Object2ReferenceMaps.UnmodifiableMap<K,V>

Returns:

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

See Also:

• Map.entrySet()

entrySet

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

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

Specified by:

entrySet in interface Map<K,V>

Specified by:

entrySet in interface Object2ReferenceMap<K,V>

Specified by:

entrySet in interface Object2ReferenceSortedMap<K,V>

Specified by:

entrySet in interface SortedMap<K,V>

Overrides:

entrySet in class Object2ReferenceMaps.UnmodifiableMap<K,V>

Returns:

a set view of the mappings contained in this map.

See Also:

• Map.entrySet()

keySet

public ObjectSortedSet<K> keySet()

Description copied from interface: Object2ReferenceMap

Specified by:

keySet in interface Map<K,V>

Specified by:

keySet in interface Object2ReferenceMap<K,V>

Specified by:

keySet in interface Object2ReferenceSortedMap<K,V>

Specified by:

keySet in interface SortedMap<K,V>

Overrides:

keySet in class Object2ReferenceMaps.UnmodifiableMap<K,V>

Returns:

a set view of the keys contained in this map.

See Also:

• Map.keySet()

subMap

public Object2ReferenceSortedMap<K,V> subMap(K from,
 K to)

Description copied from interface: Object2ReferenceSortedMap

• SortedMap.subMap(Object,Object)

headMap

public Object2ReferenceSortedMap<K,V> headMap(K to)

Description copied from interface: Object2ReferenceSortedMap

Returns a view of the portion of this sorted map whose keys are strictly less than toKey.

Specified by:
