Method Details
- containsKey
  
  public boolean containsKey(int key)
  
  Description copied from interface: Int2DoubleFunction
  
  Returns true if this function contains a mapping for the specified key.
  Note that for some kind of functions (e.g., hashes) this method will always return true. In particular, this default implementation always returns true.
  
  Specified by:
  
  containsKey in interface Int2DoubleFunction
  
  Parameters:
  
  key - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Function.containsKey(Object)
- containsKey
  
  @Deprecated public boolean containsKey(Object key)
  
  Deprecated.
  
  Description copied from interface: Int2DoubleFunction
  
  Returns true if this function contains a mapping for the specified key.
  Note that for some kind of functions (e.g., hashes) this method will always return true. This default implementation, in particular, always return true.
  
  Specified by:
  
  containsKey in interface Function<Integer,Double>
  
  Specified by:
  
  containsKey in interface Int2DoubleFunction
  
  Parameters:
  
  key - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Map.containsKey(Object)
- get
  
  public double get(int key)
  
  Description copied from interface: Int2DoubleFunction
  
  Returns the value to which the given key is mapped.
  
  Specified by:
  
  get in interface Int2DoubleFunction
  
  Parameters:
  
  key - the key.
  
  Returns:
  
  the corresponding value, or the default return value if no value was present for the given key.
  
  See Also:
  
  Function.get(Object)
- get
  
  @Deprecated public Double get(Object key)
  
  Deprecated.
  
  Description copied from interface: Int2DoubleFunction

  get in interface Function<Integer,Double>
  
  Specified by:
  
  get in interface Int2DoubleFunction
  
  Parameters:
  
  key - the key.
  
  Returns:
  
  the corresponding value, or null if no value was present for the given key.
  
  See Also:
  
  Map.get(Object)
- put
  
  @Deprecated public Double put(Integer key, Double value)
  
  Deprecated.
  
  Description copied from interface: Int2DoubleFunction
  
  Associates the specified value with the specified key in this function (optional operation).
  
  Specified by:
  
  put in interface Function<Integer,Double>
  
  Specified by:
  
  put in interface Int2DoubleFunction
  
  Parameters:
  
  key - the key.
  
  value - the value.
