public int size()
```
    Description copied from interface: Function
    
    Returns the intended number of keys in this function, or -1 if no such number exists.
    Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible.
    
    Specified by:
    
    size in interface Function<java.lang.Short,V>
    
    Specified by:
    
    size in interface java.util.Map<java.lang.Short,V>
    
    Overrides:
    
    size in class Short2ReferenceFunctions.UnmodifiableFunction<V>
    
    Returns:
    
    the intended number of keys in this function, or -1 if that number is not available.

    Returns:
    
    the current default return value.
  - defaultReturnValue
```
public void defaultReturnValue(V defRetValue)
```
    Description copied from interface: Short2ReferenceFunction
    
    Sets the default return value. This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.
    
    Specified by:
    
    defaultReturnValue in interface Short2ReferenceFunction<V>
    
    Overrides:
    
    defaultReturnValue in class Short2ReferenceFunctions.UnmodifiableFunction<V>
    
    Parameters:
    
    defRetValue - the new default return value.

  - put
```
public V put(short k,
             V v)
```
    Description copied from interface: Short2ReferenceFunction
    
    Adds a pair to the map.
    
    Specified by:
    
    put in interface Short2ReferenceFunction<V>
    
    Overrides:
    
    put in class Short2ReferenceFunctions.UnmodifiableFunction<V>
    
    Parameters:
    
    k - the key.
    
    v - the value.
    
    Returns:
    
    the old value, or the default return value if no value was present for the given key.

    putAll in interface java.util.Map<java.lang.Short,V>
  - short2ReferenceEntrySet
```
public ObjectSet<Short2ReferenceMap.Entry<V>> short2ReferenceEntrySet()
```
    Description copied from interface: Short2ReferenceMap
    
    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 Short2ReferenceMap.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:
    
    short2ReferenceEntrySet in interface Short2ReferenceMap<V>
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.

  - keySet
```
public ShortSet keySet()

public V remove(java.lang.Object k)

    Delegates to the corresponding type-specific method, taking care of returning null on a missing key.
    This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.
