Properties:

• public double alpha { get; }
  The alpha value as computed by the alpha function.
• public ulong mode { get; set construct; }
  The progress function logical id - either a value from the AnimationMode enumeration or a value returned by register_func.
• public Timeline timeline { get; set; }
  A Timeline instance used to drive the alpha function.

Static methods:

• public static ulong register_closure (Closure closure)
  Closure variant of register_func.
• public static ulong register_func (AlphaFunc func)
  Registers a global alpha function and returns its logical id to be used by set_mode or by Animation.

Creation methods:

• public Alpha ()
  Creates a new Alpha instance.
• public Alpha.full (Timeline timeline, ulong mode)
  Creates a new Alpha instance and sets the timeline and animation mode.
• public Alpha.with_func (Timeline timeline, owned AlphaFunc func)
  Creates a new Alpha instances and sets the timeline and the alpha function.

Methods:

• public double get_alpha ()
  Query the current alpha value.
• public ulong get_mode ()
  Retrieves the AnimationMode used by this.
• public unowned Timeline get_timeline ()
  Gets the Timeline bound to this.
• public void set_closure (Closure closure)
  Sets the Closure used to compute the alpha value at each frame of the Timeline bound to this.
• public void set_func (owned AlphaFunc func)
  Sets the AlphaFunc function used to compute the alpha value at each frame of the Timeline bound to this.
• public void set_mode (ulong mode)
  Sets the progress function of this using the symbolic value of mode, as taken by the AnimationMode enumeration or using the value returned by register_func.
• public void set_timeline (Timeline timeline)
  Binds this to timeline.
