Method Detail

setTime

public boolean setTime(PsTimeEvent time)

Animation updates the dynamic object through this method whenever time has changed.

Specified by:

setTime in interface PsTimeListenerIf

Parameters:

time - Time event issued by an animation

getAnimation

public PsAnimation getAnimation()

Get the animation object of the project which handles the projects animations. This listener may only have a single animation object which is assigned by the animation object when this listener is registered using setAnimation(PsAnimation).

Specified by:

getAnimation in interface PsTimeListenerIf

See Also:

hasAnimation(), setAnimation(PsAnimation)

hasAnimation

public boolean hasAnimation()

Check whether this project is registered as listener of an animation object.

Specified by:

hasAnimation in interface PsTimeListenerIf

See Also:

getAnimation(), setAnimation(PsAnimation)

setAnimation

public void setAnimation(PsAnimation anAnimation)

Assign the animation object where this listener is registered. This method is invoked by the animation object during registration of this listener, and usually is not required to be called by a user. If this listener has an assigned animation object, then its animation panel may be shown to change the current time of this listener.

Only one animation object may be assigned to this listener. Subsequent assignments will replace the previous assignment.

Specified by:

setAnimation in interface PsTimeListenerIf
