Method Details
- containsValue
  
  public boolean containsValue(short v)
  
  Description copied from interface: Int2ShortMap
  
  Returns true if this map maps one or more keys to the specified value.
  
  Specified by:
  
  containsValue in interface Int2ShortMap
  
  See Also:
  
  Map.containsValue(Object)
- containsValue
  
  @Deprecated public boolean containsValue(Object ov)
  
  Deprecated.
  Please use the corresponding type-specific method instead.
  
  Specified by:
  
  containsValue in interface Int2ShortMap
  
  Specified by:
  
  containsValue in interface Map<Integer,Short>
- putAll
  
  public void putAll(Map<? extends Integer,? extends Short> m)
  
  Specified by:
  
  putAll in interface Map<Integer,Short>
- int2ShortEntrySet
  
  public ObjectSet<Int2ShortMap.Entry> int2ShortEntrySet()
  
  Description copied from interface: Int2ShortMap
  
  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 an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).
  
  Specified by:
  
  int2ShortEntrySet in interface Int2ShortMap
  
  Returns:
  
  a type-specific set view of the mappings contained in this map.
  
  See Also:
  
  Map.entrySet()
- keySet
  
  public IntSet keySet()
  
  Description copied from interface: Int2ShortMap
  
  Note that this specification strengthens the one given in Map.keySet().
  
  Specified by:
  
  keySet in interface Int2ShortMap
  
  Specified by:
  
  keySet in interface Map<Integer,Short>
  
  Returns:
  
  a set view of the keys contained in this map.
  
  See Also:
  
  Map.keySet()
- values
  
  public ShortCollection values()
  
  Description copied from interface: Int2ShortMap
  
  Note that this specification strengthens the one given in Map.values().
  
  Specified by:
  
  values in interface Int2ShortMap
  
  Specified by:
  
  values in interface Map<Integer,Short>
  
  Returns:
  
  a set view of the values contained in this map.

  Map.values()
- clone
  
  public Object clone()
  
  Overrides:
  
  clone in class Int2ShortFunctions.EmptyFunction
- isEmpty
  
  public boolean isEmpty()
  
  Specified by:
  
  isEmpty in interface Map<Integer,Short>
- hashCode
  
  public int hashCode()
  
  Specified by:
  
  hashCode in interface Map<Integer,Short>
  
  Overrides:
  
  hashCode in class Int2ShortFunctions.EmptyFunction
- equals
  
  public boolean equals(Object o)
  
  Specified by:
  
  equals in interface Map<Integer,Short>
  
  Overrides:
  
  equals in class Int2ShortFunctions.EmptyFunction
- toString
  
  public String toString()
  
  Overrides:
  
  toString in class Int2ShortFunctions.EmptyFunction
