public static class Byte2ReferenceMaps.Singleton<V>
extends Byte2ReferenceFunctions.Singleton<V>
implements Byte2ReferenceMap<V>, 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.

protected Byte2ReferenceMaps.Singleton(byte key,
                                       V value)
Method Detail

containsValue

public boolean containsValue(Object v)
Specified by:
containsValue in interface Map<Byte,V>

putAll

public void putAll(Map<? extends Byte,? extends V> m)
Specified by:
putAll in interface Map<Byte,V>

byte2ReferenceEntrySet

public ObjectSet<Byte2ReferenceMap.Entry<V>> byte2ReferenceEntrySet()
Description copied from interface: Byte2ReferenceMap
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 Byte2ReferenceMap.entrySet() so that it returns an ObjectSet of objects of type Byte2ReferenceMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:
byte2ReferenceEntrySet in interface Byte2ReferenceMap<V>
Returns:
a type-specific set view of the mappings contained in this map.
See Also:
Byte2ReferenceMap.entrySet()

keySet

public ByteSet keySet()
Description copied from interface: Byte2ReferenceMap
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 Byte2ReferenceMap<V>
Specified by:
keySet in interface Map<Byte,V>
Returns:
a set view of the keys contained in this map.
See Also:
Map.keySet()

values

public ReferenceCollection<V> values()
Description copied from interface: Byte2ReferenceMap
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 Byte2ReferenceMap<V>
Specified by:
values in interface Map<Byte,V>
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<Byte,V>

entrySet

public ObjectSet<Map.Entry<Byte,V>> entrySet()
Description copied from interface: Byte2ReferenceMap
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 Byte2ReferenceMap<V>
Specified by:
entrySet in interface Map<Byte,V>
Returns:
a set view of the mappings contained in this map.
See Also:
Map.entrySet()

hashCode

public int hashCode()
Specified by:
hashCode in interface Map<Byte,V>
Overrides:
hashCode in class Object

equals

public boolean equals(Object o)
Specified by:
equals in interface Map<Byte,V>
Overrides:
equals in class Object

toString

public String toString()
Overrides:
toString in class Object
