Object2ObjectSortedMaps

public static class Object2ObjectSortedMaps.Singleton<K,V>
extends Object2ObjectMaps.Singleton<K,V>

An immutable class representing a type-specific singleton sorted map.

This class may be useful to implement your own in case you subclass a type-specific sorted map.

Method Detail

comparator

public Comparator<? super K> comparator()

Description copied from interface: Object2ObjectSortedMap

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 Object2ObjectSortedMap<K,V>

Specified by:

comparator in interface SortedMap<K,V>

See Also:

SortedMap.comparator()

object2ObjectEntrySet

public ObjectSortedSet<Object2ObjectMap.Entry<K,V>> object2ObjectEntrySet()

Description copied from interface: Object2ObjectMap

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 Object2ObjectMap.entrySet() so that it returns an ObjectSet of objects of type Object2ObjectMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

object2ObjectEntrySet in interface Object2ObjectMap<K,V>

Specified by:

object2ObjectEntrySet in interface Object2ObjectSortedMap<K,V>

Overrides:

object2ObjectEntrySet in class Object2ObjectMaps.Singleton<K,V>

Returns:

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

See Also:

Object2ObjectMap.entrySet()

entrySet

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

Description copied from interface: Object2ObjectMap

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 Object2ObjectMap<K,V>

Specified by:

entrySet in interface Object2ObjectSortedMap<K,V>

Specified by:

entrySet in interface Map<K,V>

Overrides:

entrySet in class Object2ObjectMaps.Singleton<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: Object2ObjectMap

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 Object2ObjectMap<K,V>

Specified by:

keySet in interface Object2ObjectSortedMap<K,V>

Specified by:

keySet in interface Map<K,V>

Overrides:

keySet in class Object2ObjectMaps.Singleton<K,V>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Object2ObjectSortedMap<K,V> subMap(K from,
                                          K to)

Description copied from interface: Object2ObjectSortedMap

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 Object2ObjectSortedMap<K,V>

Specified by:

subMap in interface SortedMap<K,V>

See Also:

SortedMap.subMap(Object,Object)

headMap

public Object2ObjectSortedMap<K,V> headMap(K to)

Description copied from interface: Object2ObjectSortedMap

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:

headMap in interface Object2ObjectSortedMap<K,V>

Specified by:

headMap in interface SortedMap<K,V>

See Also:

SortedMap.headMap(Object)

tailMap

public Object2ObjectSortedMap<K,V> tailMap(K from)

Description copied from interface: Object2ObjectSortedMap

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).

Specified by:

tailMap in interface Object2ObjectSortedMap<K,V>
