Method Details
- 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,Byte>
  
  Returns:
  
  the intended number of keys in this function, or -1 if that number is not available.
- defaultReturnValue
  
  public byte defaultReturnValue()
  
  Description copied from interface: Double2ByteFunction
  
  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 Double2ByteFunction
  
  Overrides:
  
  defaultReturnValue in class AbstractDouble2ByteFunction
  
  Returns:
  
  the current default return value.
- defaultReturnValue
  
  public void defaultReturnValue(byte defRetValue)
  
  Description copied from interface: Double2ByteFunction
  
  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 Double2ByteFunction
  
  Overrides:
  
  defaultReturnValue in class AbstractDouble2ByteFunction
  
  Parameters:
  
  defRetValue - the new default return value.
  
  See Also:
  
  Double2ByteFunction.defaultReturnValue()
- containsKey
  
  public boolean containsKey(double k)
  
  Description copied from interface: Double2ByteFunction
  
  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 Double2ByteFunction
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Function.containsKey(Object)
- put
  
  public byte put(double k, byte v)
  
  Description copied from interface: Double2ByteFunction
  
  Adds a pair to the map (optional operation).
  
  Specified by:
  
  put in interface Double2ByteFunction
  
  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.
  
  See Also:
  
  Function.put(Object,Object)
- get
  
  public byte get(double k)
  
  Description copied from interface: Double2ByteFunction
  
  Returns the value to which the given key is mapped.
  
  Specified by:
  
  get in interface Double2ByteFunction
  
  Parameters:
  
  k - 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)
- remove
  
  public byte remove(double k)
  
  Description copied from interface: Double2ByteFunction
  
  Removes the mapping with the given key (optional operation).
  
  Specified by:
  
  remove in interface Double2ByteFunction
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  the old value, or the default return value if no value was present for the given key.
  
  See Also:
  
  Function.remove(Object)
- clear
  
  public void clear()
  
  Description copied from interface: Function
  
  Removes all associations from this function (optional operation).
  
  Specified by:
  
  clear in interface Function<Double,Byte>
  
  See Also:
  
  Map.clear()
- put
  
  @Deprecated public Byte put(Double k, Byte v)
  
  Deprecated.
  Please use the corresponding type-specific method instead.
  
  Associates the specified value with the specified key in this function (optional operation).
  
  Specified by:
  
  put in interface Double2ByteFunction
  
  Specified by:
  
  put in interface Function<Double,Byte>
  
  Parameters:
  
  k - the key.
  
  v - the value.

  Map.put(Object,Object)
- get
  
  @Deprecated public Byte get(Object k)
  
  Deprecated.
  Please use the corresponding type-specific method instead.
  
  Returns the value associated by this function to the specified key.
  
  Specified by:
  
  get in interface Double2ByteFunction
  
  Specified by:
  
  get in interface Function<Double,Byte>
  
  Parameters:
  
  k - the key.

  the corresponding value, or null if no value was present for the given key.
  
  See Also:
  
  Map.get(Object)
- remove
  
  @Deprecated public Byte remove(Object k)
  
  Deprecated.
  Please use the corresponding type-specific method instead.
