Method Detail

comparator

public Comparator<? super K> comparator()

Description copied from interface: Reference2ReferenceSortedMap

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 Reference2ReferenceSortedMap<K,V>

Specified by:

comparator in interface SortedMap<K,V>

See Also:

SortedMap.comparator()

reference2ReferenceEntrySet

public ObjectSortedSet<Reference2ReferenceMap.Entry<K,V>> reference2ReferenceEntrySet()

Description copied from interface: Reference2ReferenceMap

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 Reference2ReferenceMap.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:

reference2ReferenceEntrySet in interface Reference2ReferenceMap<K,V>

Specified by:

reference2ReferenceEntrySet in interface Reference2ReferenceSortedMap<K,V>

Overrides:

reference2ReferenceEntrySet in class Reference2ReferenceMaps.UnmodifiableMap<K,V>

Returns:

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

See Also:

Reference2ReferenceMap.entrySet()

entrySet

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

Description copied from interface: Reference2ReferenceMap

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 Reference2ReferenceMap<K,V>

Specified by:

entrySet in interface Reference2ReferenceSortedMap<K,V>

Specified by:

entrySet in interface Map<K,V>

Specified by:

entrySet in interface SortedMap<K,V>

Overrides:

entrySet in class Reference2ReferenceMaps.UnmodifiableMap<K,V>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public ReferenceSortedSet<K> keySet()

Description copied from interface: Reference2ReferenceMap

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 Reference2ReferenceMap<K,V>

Specified by:

keySet in interface Reference2ReferenceSortedMap<K,V>

Specified by:

keySet in interface Map<K,V>

Specified by:

keySet in interface SortedMap<K,V>

Overrides:

keySet in class Reference2ReferenceMaps.UnmodifiableMap<K,V>

Returns:

a set view of the keys contained in this map.

Map.keySet()

subMap

public Reference2ReferenceSortedMap<K,V> subMap(K from,
                                       K to)

Description copied from interface: Reference2ReferenceSortedMap

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 Reference2ReferenceSortedMap<K,V>

subMap in interface SortedMap<K,V>

headMap

public Reference2ReferenceSortedMap<K,V> headMap(K to)

Description copied from interface: Reference2ReferenceSortedMap

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:

tailMap

public Reference2ReferenceSortedMap<K,V> tailMap(K from)

Description copied from interface: Reference2ReferenceSortedMap

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).
