Interface IlvObjectAnimator

All Known Implementing Classes:

IlvGraphicAnimator, IlvLinkImageAnimator

public interface IlvObjectAnimator

The interface IlvObjectAnimator must be implemented by a class whose purpose is to animate one object of an IlvManager with an IlvManagerAnimator. When the IlvManagerAnimator is attached to the IlvManager, an IlvObjectAnimator is created for each object managed by the manager to support animation. The object animator stores the information on the current state of the object (such as position, size, and so on) using the method recordState. It can also display the movement of the object from the recorded state to the current state using the method animInit and iterative calls to the method animStep.

Since:

JViews 6.0

Method Summary

Modifier and Type	Method and Description
void	animCleanup() Cleans up animation.
void	animInit() Initializes animation.
boolean	animStep(IlvManager manager, int i, int maxI) This method is called in the ith animation step.
void	recordState() Records the current state of the object (such as position, size, and so on) in the object animator.

Method Detail

recordState

void recordState()

Records the current state of the object (such as position, size, and so on) in the object animator. This method is called by IlvManagerAnimator.recordState(). An animation sequence always shows the movement between the previously recorded state and the current state.

See Also:

IlvManagerAnimator.recordState()

animInit

void animInit()

Initializes animation. This method is called before the first step of animate is performed.

See Also:

IlvManagerAnimator.animate()

animCleanup

void animCleanup()

Cleans up animation. This method is called after the last step of animate is performed.

See Also:

IlvManagerAnimator.animate()

animStep

boolean animStep(IlvManager manager,
                 int i,
                 int maxI)

This method is called in the ith animation step. It is called in a loop from i = 1 to i = maxI by IlvManagerAnimator.animate() to show animated movement, for example, moving or resizing objects in small steps. It returns true if animation must continue for this object, false if animation is finished for this object after the ith step.

Parameters:

manager - The manager that contains the graphic to be animated.

i - The number of the current animation step.

maxI - The maximum number of animation steps.
