TimeContainerRootSupport

• java.lang.Object
  • TimeContainerSupport

Fields Summary
protected long	beginWallClockTime The time at which the document started. This is initially set when animation is started and then modified when the document's timeline is seeked to a particular time.
protected Time	lastSampleTime The last sample time.
protected boolean	seekingBack Flags that the seek is backwards

Constructors Summary
TimeContainerRootSupport() There is no parent container for this root. The parent is this node itself. Also, the root time container has a default 0-offset begin condition added to it so that the first interval is created and is [0, INDEFINITE[. timeContainer = this; // Add a new 0-offset begin condition. new OffsetCondition(this, true, 0);

Methods Summary
void	dispatchBeginEvent(Time beginTime) Dispatches beginEvent. See the TimedElementSupport class method implementation. This class also uses the opportunity to record what the wallclock time is for the begin time so that localTimes can be converted later. param beginTime the interval begin time super.dispatchBeginEvent(beginTime); beginWallClockTime = System.currentTimeMillis(); // With the following, beginTime will map to beginWallClockTime, // as expected. beginWallClockTime -= beginTime.value;
Time	getContainerSimpleDuration() For the root container, there is no container simple duration, so we retun INDEFINITE, no matter what the state is. return the container's simple duration. return Time.INDEFINITE;
com.sun.perseus.model.TimeContainerRootSupport	getRootContainer() Helper method. return this timed element's root container. return this;
void	sample(Time currentTime) Overrides the default sample time to capture the last sample time. param currentTime the time at which this element should be sampled. super.sample(currentTime); lastSampleTime = currentTime;
void	seekTo(Time seekToTime) Seek to the requested time. The time is assumed to be in document simple time. param seekToTime the time to seek to if (!seekToTime.isResolved()) { throw new IllegalStateException(); } seeking = true; seekingBack = !seekToTime.greaterThan(lastSampleTime); try { sample(seekToTime); } finally { seeking = false; }
protected void	setTimeContainer(TimeContainerSupport timeContainer) Always throws an exception because a root container should not have a parent container. param timeContainer time container throws IllegalArgumentException always thrown for a root time container which should not have a parent container. throw new IllegalArgumentException();
Time	toContainerSimpleTime(Time rootSimpleTime) Converts the input root container simple time (i.e., a time in the root container's simple time interval) to a time in this element's time container simple duration. param rootSimpleTime the time in the root container's simple duration. return a simple time in the parent container's simple duration The return value is in the [0, container simple duration] interval. return rootSimpleTime;
Time	toRootContainerSimpleTime(Time simpleTime) Converts the input simple time (i.e., a time in the parent container's simple duration) to a root container simple time (i.e., a time in the root time container's simple time interval). param simpleTime the time in the parent container's simple duration return a time in the root time container's simple duration (i.e., in the root container's simple time interval). return simpleTime;
Time	toRootContainerSimpleTimeClamp(Time simpleTime) Converts the input simple time (i.e., a time in the parent container's simple duration) to a root container simple time (i.e., a time in the root time container's simple time interval). param simpleTime the time in the parent container's simple duration return a time in the root time container's simple duration (i.e., in the root container's simple time interval). // Note that no clamping is necessary here because the clamping is // done in a timed element, relative to its container's simple time. // By the time this is called on the root, the child timed element has // already applied the root's constraints. return simpleTime;
long	toWallClockTime(long localTime) Converts the input 'local' time to an absolute wallclock time. param localTime the time to convert to wallclock time return the time, converted to wall clock time. return beginWallClockTime + localTime;
