public void putAll(java.util.Map<? extends K,? extends java.lang.Byte> m)

    Specified by:

  - 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 Reference2ByteMap.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).
    
    Specified by:
    
    reference2ByteEntrySet in interface Reference2ByteMap<K>
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.
    
    See Also:
    
    Reference2ByteMap.entrySet()
  - keySet
```
public ReferenceSet<K> keySet()
```
    Description copied from interface: Reference2ByteMap
    
    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 Reference2ByteMap<K>
    
    Specified by:
    
    keySet in interface java.util.Map<K,java.lang.Byte>
    
    Returns:

  - values
```
public ByteCollection values()
```
    Description copied from interface: Reference2ByteMap
    
    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 Reference2ByteMap<K>
    
    Specified by:
    
    values in interface java.util.Map<K,java.lang.Byte>

public ObjectSet<java.util.Map.Entry<K,java.lang.Byte>> entrySet()
```
    Description copied from interface: Reference2ByteMap
    
    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 Reference2ByteMap<K>
    
    Specified by:
    
    entrySet in interface java.util.Map<K,java.lang.Byte>
