Class PsAnimation

All Implemented Interfaces:

java.lang.Cloneable, PsUpdateIf, java.lang.Runnable, java.io.Serializable

public class PsAnimation

extends PsObject

implements java.lang.Runnable

Animation manager issues time events and updates its listeners. Classes interested in time event must implement the interface PsTimeListenerIf and register as listeners in an instance this class.

On default, the time variable runs in the interval [0,100].

For usage, see interface PsTimeListenerIf. Since version 2.00 each animation has its own animationPanel.

Version:

21.02.01, 3.30 revised (kp) Now register this object inside its time listeners.
21.01.01, 3.20 revised (kp) Info panel subclassed from PsPanel than PsDialog.
01.12.00, 3.10 revised (kp) Implement two methods to get/set the sleep interval.
16.09.00, 3.00 revised (kp) Interface PsAnimationIf removed, static variable moved to PsAnimation.
06.10.99, 2.51 revised (ur) Let time for LOOP run in min<=time<= max instead of min 12.06.99, 2.50 revised (kp) Use name of dynamic object as title of the animation panel.
06.06.99, 2.50 revised (kp) Start/stop and m_thread handling moved here from info panel.
20.05.99, 2.00 revised (kp) Now each animation has its own animation panel.
00.00.97, 1.00 created (kp)

public static final int FAST_REWIND

Play animation with fast speed determined by page increment of time ruler in backward direction.

ONE_WAY

public static final int ONE_WAY

Stop animation, repeat mode when either end of animation is reached.

Constructor Detail

PsAnimation

public PsAnimation()

Method Detail

init

public void init()

Description copied from class: PsObject

If instance has missing name then assign default name 'object_NUMBER' where number is the total number of already created instances.

Overrides:

init in class PsObject

addTimeListener

public boolean addTimeListener(PsTimeListenerIf listener)

Register a new update listener, and in return, register this animation in the time listener. This bijective registration allows the time listener to invoke this animation panel.

Parameters:

Listener - to register

Returns:

false if listener already registered.

See Also:

hasTimeListener(PsTimeListenerIf), removeTimeListener(PsTimeListenerIf)

hasTimeListener

public boolean hasTimeListener(PsTimeListenerIf listener)

Check whether an instance is a registered listener.

Returns:

true if registered listener found.

See Also:

addTimeListener(PsTimeListenerIf), removeTimeListener(PsTimeListenerIf)

removeTimeListener

public boolean removeTimeListener(PsTimeListenerIf listener)

Remove a registered listener from list of registered listeners.

Parameters:

Registered - listener

Returns:

false if listener is not registered.

See Also:

addTimeListener(PsTimeListenerIf), hasTimeListener(PsTimeListenerIf)

getSleepInterval

public long getSleepInterval()

Get the length of the sleep interval between two timer events.
