org.apache.batik.anim.timing
Class TimedElement

java.lang.Object
  extended by org.apache.batik.anim.timing.TimedElement
All Implemented Interfaces:
SMILConstants
Direct Known Subclasses:
SVGAnimationElementBridge.SVGTimedElement, TimeContainer
public abstract class TimedElement
extends Object
implements SMILConstants

An abstract base class for elements that can have timing applied to them. The concrete versions of this class do not necessarily have to be the same as the DOM class, and in fact, this will mostly be impossible unless creating new DOM classes that inherit from these elements.

Constructor Detail

TimedElement

Creates a new TimedElement.

Method Detail

public TimedDocumentRoot getRoot()
Returns the root time container of this timed element.

getActiveTime

public float getActiveTime()
Returns the current active time of this element.

getSimpleTime

public float getSimpleTime()

                                boolean isBegin)
Called by a TimingSpecifier of this element when a new InstanceTime is created. This will be in response to an event firing, a DOM method being called or a new Instance being created by a syncbase element.

removeInstanceTime

protected float removeInstanceTime(InstanceTime time,
                                   boolean isBegin)
Called by a TimingSpecifier of this element when an InstanceTime should be removed. This will be in response to the pruning of an Interval.

                                    boolean isBegin)
Called by a TimingSpecifier of this element when an InstanceTime has been updated. This will be in response to a dependent syncbase change.

Adds a dependent TimingSpecifier for this element.

removeDependent

protected void removeDependent(TimingSpecifier dependent,
                               boolean forBegin)

public static boolean isUnresolved(float t)
Returns whether the given time value is equal to the UNRESOLVED value.

                          float end)
Returns the active duration time of this element.

minusTime

protected float minusTime(float t1,
                          float t2)
Subtracts one simple time from another.

                        float t2)

getImplicitDur

protected float getImplicitDur()
Returns the implicit duration of the element. Currently, nested time containers are not supported by SVG so this just returns UNRESOLVED by default. This should be overriden in derived classes that play media, since they will have an implicit duration.

notifyNewInterval

protected float notifyNewInterval(Interval interval)
Notifies dependents of a new interval.

notifyRemoveInterval

protected float notifyRemoveInterval(Interval interval)
Notifies dependents of a removed interval.

sampleAt

protected float sampleAt(float parentSimpleTime,
                         boolean hyperlinking)
Calculates the local simple time. Currently the hyperlinking parameter is ignored, so DOM timing events are fired during hyperlinking seeks. If we were following SMIL 2.1 rather than SMIL Animation, then these events would have to be suppressed.

Returns:
the number of seconds until this element becomes active again if it currently is not, Float.POSITIVE_INFINITY if this element will become active at some undetermined point in the future (because of unresolved begin times, for example) or will never become active again, or 0f if the element is currently active.

endHasEventConditions

protected boolean endHasEventConditions()
Returns whether the end timing specifier list contains any eventbase, accesskey or repeat timing specifiers.

selectNewInterval

protected float selectNewInterval(float time,
                                  Interval interval)
Sets the current interval to the one specified. This will notify dependents and fire the 'begin' and any necessary 'repeat' events.

Parameters:
time - the current sampling time
interval - the Interval object to select to be current
Returns:
the minimum time the animation engine can safely wait, as determined by dependents of the interval

computeInterval

protected Interval computeInterval(boolean first,
                                   boolean fixedBegin,

                                   boolean incl)
Computes an interval from the begin and end instance time lists.

fixedBegin - if true, specifies that the value given for beginAfter is taken to be the actual begin time for the interval; only the end value is computed.
beginAfter - the earliest possible begin time for the computed interval.
