Method Details
- apply
  
  public V apply(double operand)
  
  Description copied from interface: Double2ReferenceFunction
  
  Specified by:
  
  apply in interface Double2ReferenceFunction<V>
  
  Specified by:
  
  apply in interface DoubleFunction<V>
- apply
  
  @Deprecated public V apply(Double key)
  
  Deprecated.
  Please use the corresponding type-specific method instead.
  
  This is equivalent to calling Function.get(Object).
  
  Specified by:
  
  apply in interface Function<Double,V>
  
  Specified by:
  
  apply in interface Function<Double,V>
  
  Parameters:
  
  key -
  
  Returns:
  
  See Also:
  
  Function.apply(Object), Function.get(Object)
- size
  
  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. This default implementation, in particular, returns -1.
  
  Specified by:
  
  size in interface Function<Double,V>
  
  Returns:
  
  the intended number of keys in this function, or -1 if that number is not available.
- defaultReturnValue
  
  public V defaultReturnValue()
  
  Description copied from interface: Double2ReferenceFunction
  
  Gets the default return value.
  This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).
  
  Specified by:
  
  defaultReturnValue in interface Double2ReferenceFunction<V>
  
  Returns:
  
  the current default return value.
- defaultReturnValue
  
  public void defaultReturnValue(V defRetValue)
  
  Description copied from interface: Double2ReferenceFunction
  
  Sets the default return value (optional operation). 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 Double2ReferenceFunction<V>
  
  Parameters:
  
  defRetValue - the new default return value.
  
  See Also:
  
  Double2ReferenceFunction.defaultReturnValue()
- containsKey
  
  public boolean containsKey(double k)
  
  Description copied from interface: Double2ReferenceFunction
  
  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 Double2ReferenceFunction<V>
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Function.containsKey(Object)
- containsKey
  
  @Deprecated public boolean containsKey(Object k)
  
  Deprecated.
  
  Description copied from interface: Double2ReferenceFunction
  
  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 Double2ReferenceFunction<V>
  
  Specified by:
  
  containsKey in interface Function<Double,V>
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Map.containsKey(Object)
- put
  
  public V put(double k, V v)
  
  Description copied from interface: Double2ReferenceFunction
  
  Adds a pair to the map (optional operation).
