Method Details
- containsKey
  
  public boolean containsKey(float key)
  
  Description copied from interface: Float2DoubleFunction
  
  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 Float2DoubleFunction
  
  Parameters:
  
  key - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Function.containsKey(Object)
- containsKey
  
  @Deprecated public boolean containsKey(java.lang.Object key)
  
  Deprecated.
  
  Description copied from interface: Float2DoubleFunction
  
  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 Float2DoubleFunction
  
  Specified by:
  
  containsKey in interface Function<java.lang.Float,java.lang.Double>
  
  Parameters:
  
  key - the key.
  
  Returns:
  
  true if this function associates a value to key.

  Map.containsKey(Object)
- get
  
  public double get(float key)
  
  Description copied from interface: Float2DoubleFunction
  
  Returns the value to which the given key is mapped.
  
  Specified by:
  
  get in interface Float2DoubleFunction
  
  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)
- getOrDefault
  
  public double getOrDefault(float key, double defaultValue)
  
  Description copied from interface: Float2DoubleFunction
  
  Returns the value associated by this function to the specified key, or give the specified value if not present.
  
  Specified by:
  
  getOrDefault in interface Float2DoubleFunction
  
  Parameters:
  
  key - the key.
  
  defaultValue - the value to return if not present.
  
  Returns:
  
  the corresponding value, or defaultValue if no value was present for the given key.
