public static class Object2ShortMaps.Singleton<K>
extends Object2ShortFunctions.Singleton<K>
implements Object2ShortMap<K>, Serializable, Cloneable

An immutable class representing a type-specific singleton map.

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

Map.containsValue(Object)

containsValue

object2ShortEntrySet

public ObjectSet<Object2ShortMap.Entry<K>> object2ShortEntrySet()

Description copied from interface: Object2ShortMap

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 Object2ShortMap.entrySet() so that it returns an ObjectSet of objects of type Object2ShortMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

object2ShortEntrySet in interface Object2ShortMap<K>

Returns:

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

See Also:

Object2ShortMap.entrySet()

keySet

public ObjectSet<K> keySet()

Description copied from interface: Object2ShortMap

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 Object2ShortMap<K>

Specified by:

keySet in interface Map<K,Short>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public ShortCollection values()

Description copied from interface: Object2ShortMap

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

Note that this specification strengthens the one given in Map.values().

Specified by:

values in interface Object2ShortMap<K>

Specified by:

values in interface Map<K,Short>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<K,Short>

entrySet

public ObjectSet<Map.Entry<K,Short>> entrySet()

Description copied from interface: Object2ShortMap

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 Object2ShortMap<K>

Specified by:

entrySet in interface Map<K,Short>

Returns:

a set view of the mappings contained in this map.

Specified by:

hashCode in interface Map<K,Short>

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<K,Short>

Overrides:

equals in class Object
