Interface PsKeyframeIf

All Known Implementing Classes:

PsKeyframe

public interface PsKeyframeIf

Additional interface for dynamic objects to allow stepping through keyframes. This methods are called from animation panel to allow viewing and stepping through set of keyframes.

Interface may be implemented additionally to PsTimeListenerIf. In this case, if a dynamic object is registered inside an animation object, then the animation panel has buttons enabled which allow stepping through keyframes.

Version:

02.01.00, 1.00 revised (kp)
02.01.00, 1.00 created (kp) From methods getTimeOf..Key() of PsTimeListenerIf.

Method Summary

double	getTimeOfFirstKey() Minimal value of animation interval if instance has keyframes.
double	getTimeOfLastKey() Maximal value of animation interval if instance has keyframes.
double	getTimeOfNextKey() Current time plus time step increment if instance has keyframes.
double	getTimeOfPreviousKey() Current time minus time step increment if instance has keyframes.

Method Detail

getTimeOfFirstKey

public double getTimeOfFirstKey()

Minimal value of animation interval if instance has keyframes. Specific for keyframe animations, otherwise default implementations suffice. Method is invoked from animation panel to browse through set of keys.

PsAnimation.enableKeys(boolean)

getTimeOfPreviousKey

public double getTimeOfPreviousKey()

Current time minus time step increment if instance has keyframes. Specific for keyframe animations, otherwise default implementations suffice. Method is invoked from animation panel to browse through set of keys.

getTimeOfNextKey

public double getTimeOfNextKey()

Current time plus time step increment if instance has keyframes. Specific for keyframe animations, otherwise default implementations suffice.

See Also:

PsAnimation.enableKeys(boolean)

getTimeOfLastKey

public double getTimeOfLastKey()

Maximal value of animation interval if instance has keyframes. Specific for keyframe animations, otherwise default implementations suffice.
