public abstract class Interpolator
extends Behavior

Interpolator is an abstract class that extends Behavior to provide common methods used by various interpolation subclasses. These include methods to convert a time value into an alpha value (A value in the range 0 to 1) and a method to initialize the behavior. Subclasses provide the methods that convert alpha values into values within that subclass' output range.

Constructor Detail

Interpolator

public Interpolator()

Constructs an Interpolator node with a null alpha value.

Interpolator

public Interpolator(Alpha alpha)

Constructs an Interpolator node with the specified alpha value.

Parameters:

alpha - the alpha object used by this interpolator. If it is null, then this interpolator will not run.

Method Detail

getAlpha

public Alpha getAlpha()

Retrieves this interpolator's alpha object.

Returns:

this interpolator's alpha object

setAlpha

public void setAlpha(Alpha alpha)

Set this interpolator's alpha to the specified alpha object.

Parameters:

alpha - the new alpha object. If set to null, then this interpolator will stop running.

initialize

public void initialize()

This is the default Interpolator behavior initialization routine. It schedules the behavior to awaken at the next frame.

Specified by:

initialize in class Behavior
