public static class Reference2ByteMaps.Singleton<K> extends Reference2ByteFunctions.Singleton<K> implements Reference2ByteMap<K>, java.io.Serializable, java.lang.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)
Description copied from interface:Reference2ByteMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceReference2ByteMap<K>
- See Also:
Map.containsValue(Object)
-
containsValue
@Deprecated public boolean containsValue(java.lang.Object ov)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
containsValue
in interfacejava.util.Map<K,java.lang.Byte>
- Specified by:
containsValue
in interfaceReference2ByteMap<K>
-
putAll
public void putAll(java.util.Map<? extends K,? extends java.lang.Byte> m)
- Specified by:
putAll
in interfacejava.util.Map<K,java.lang.Byte>
-
reference2ByteEntrySet
public ObjectSet<Reference2ByteMap.Entry<K>> reference2ByteEntrySet()
Description copied from interface:Reference2ByteMap
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
Map.entrySet()
so that it returns anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
reference2ByteEntrySet
in interfaceReference2ByteMap<K>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
@Deprecated public ObjectSet<java.util.Map.Entry<K,java.lang.Byte>> entrySet()
Deprecated.Please use the corresponding type-specific method instead.Returns a set view of the mappings contained in this map.- Specified by:
entrySet
in interfacejava.util.Map<K,java.lang.Byte>
- Specified by:
entrySet
in interfaceReference2ByteMap<K>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public ReferenceSet<K> keySet()
Description copied from interface:Reference2ByteMap
- Specified by:
keySet
in interfacejava.util.Map<K,java.lang.Byte>
- Specified by:
keySet
in interfaceReference2ByteMap<K>
- Returns:
- a set view of the keys contained in this map.
- See Also:
