Class AbstractAnimation

public abstract class AbstractAnimation extends Object

An abstract base class for the different types of animation.

Field Summary
protected AnimatableElement	animatableElement The AnimatableElement that gives access to underlying values in the document.
protected float	beginTime The time at which this animation became active.
protected AnimatableValue	composedValue The value of this animation composed with any others.
static short	CALC_MODE_DISCRETE
static short	CALC_MODE_LINEAR
static short	CALC_MODE_PACED
static short	CALC_MODE_SPLINE
protected AbstractAnimation	higherAnimation The animation that is higher in the sandwich.
protected boolean	isActive Whether this animation is active.
protected boolean	isDirty Whether this animation needs recomputing.
protected boolean	isFrozen Whether this animation is frozen.
protected AbstractAnimation	lowerAnimation The animation that is lower in the sandwich.
protected TimedElement	timedElement The TimedElement that controls the timing of this animation.
protected boolean	toAnimation Whether this animation is a 'to-animation'.
protected boolean	usesUnderlyingValue Whether this animation depends on the underlying value.
protected AnimatableValue	value The value of this animation.

Constructor Summary
protected	AbstractAnimation(TimedElement timedElement, AnimatableElement animatableElement) Creates a new Animation.

Method Summary
AnimatableValue	getComposedValue() Returns the composed value of this animation, or null if it isn't active.
TimedElement	getTimedElement() Returns the TimedElement for this animation.
AnimatableValue	getValue() Returns the value of this animation, or null if it isn't active.
protected void	markDirty() Marks this animation and any animation that depends on it as dirty.
protected abstract void	sampledAt(float simpleTime, float simpleDur, int repeatIteration) Called when the element is sampled at the given time.
protected void	sampledLastValue(int repeatIteration) Called when the element is sampled for its "last" value.
String	toString() Returns a string representation of this animation.
boolean	usesUnderlyingValue() Returns whether this animation depends on the underlying value.
protected boolean	willReplace() Returns whether this animation will replace values on animations lower in the sandwich.

Field Detail

animatableElement

protected AnimatableElement animatableElement

The AnimatableElement that gives access to underlying values in the document.

beginTime

protected float beginTime

The time at which this animation became active. Used for ensuring the sandwich order is correct when multiple animations become active simultaneously.
