Method Details
- containsKey
  
  public boolean containsKey(double key)
  
  Description copied from interface: Double2ObjectFunction
  
  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 Double2ObjectFunction<V>
  
  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: Double2ObjectFunction
  
  Returns true if this function contains a mapping for the specified key.

  Specified by:
  
  containsKey in interface Function<Double,V>
  
  Parameters:
  
  key - the key.
  
  Returns:
  
  true if this function associates a value to key.

- get
  
  public V get(double key)
  
  Description copied from interface: Double2ObjectFunction
  
  Returns the value to which the given key is mapped.
  
  Specified by:
  
  get in interface Double2ObjectFunction<V>
  
  Parameters:
  
  key - the key.
  
  Returns:
  
  the corresponding value, or the default return value if no value was present for the given key.

  Specified by:
  
  getOrDefault in interface Double2ObjectFunction<V>
  
  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.
