public static class Long2ByteMaps.Singleton
extends Long2ByteFunctions.Singleton
implements Long2ByteMap, 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.

Method Detail

containsValue

public boolean containsValue(byte v)
Specified by:
containsValue in interface Long2ByteMap
See Also:
Map.containsValue(Object)

containsValue

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

putAll

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

long2ByteEntrySet

public ObjectSet<Long2ByteMap.Entry> long2ByteEntrySet()
Description copied from interface: Long2ByteMap
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 Long2ByteMap.entrySet() so that it returns an ObjectSet of objects of type Long2ByteMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:
long2ByteEntrySet in interface Long2ByteMap
Returns:
a type-specific set view of the mappings contained in this map.
See Also:
Long2ByteMap.entrySet()

keySet

public LongSet keySet()
Description copied from interface: Long2ByteMap
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 Long2ByteMap
Specified by:
keySet in interface Map<Long,Byte>
Returns:
a set view of the keys contained in this map.
See Also:
Map.keySet()

values

public ByteCollection values()
Description copied from interface: Long2ByteMap
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 Long2ByteMap
Specified by:
values in interface Map<Long,Byte>
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<Long,Byte>

entrySet

public ObjectSet<Map.Entry<Long,Byte>> entrySet()
Description copied from interface: Long2ByteMap
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 Long2ByteMap
Specified by:
entrySet in interface Map<Long,Byte>
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<Long,Byte>
Overrides:
hashCode in class Object

equals

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

toString

public String toString()
Overrides:
toString in class Object
