Constructor Detail

SVGAnimationEngine.AnimationRoot

public SVGAnimationEngine.AnimationRoot()
Creates a new AnimationRoot object.

Method Detail

getEventNamespaceURI

protected String getEventNamespaceURI(String eventName)
Returns the namespace URI of the event that corresponds to the given animation event name.

Specified by:
getEventNamespaceURI in class TimedDocumentRoot

getEventType

protected String getEventType(String eventName)
Returns the type of the event that corresponds to the given animation event name.

Specified by:
getEventType in class TimedDocumentRoot

getRepeatEventName

protected String getRepeatEventName()
Returns the name of the repeat event.

Specified by:
getRepeatEventName in class TimedDocumentRoot
Returns:
"repeatEvent" for SVG

fireTimeEvent

protected void fireTimeEvent(String eventType,
                             Calendar time,
                             int detail)
Fires a TimeEvent of the given type on this element.

Specified by:
fireTimeEvent in class TimedElement
Parameters:
eventType - the type of TimeEvent ("beginEvent", "endEvent" or "repeatEvent"/"repeat").
time - the timestamp of the event object

toActive

protected void toActive(float begin)
Invoked to indicate this timed element became active at the specified time.

Specified by:
toActive in class TimedElement
Parameters:
begin - the time the element became active, in document simple time

toInactive

protected void toInactive(boolean stillActive,
                          boolean isFrozen)
Invoked to indicate that this timed element became inactive.

Specified by:
toInactive in class TimedElement
Parameters:
stillActive - if true, indicates that the element is still actually active, but between the end of the computed repeat duration and the end of the interval
isFrozen - whether the element is frozen or not

removeFill

protected void removeFill()
Invoked to indicate that this timed element has had its fill removed.

Specified by:
removeFill in class TimedElement

sampledAt

protected void sampledAt(float simpleTime,
                         float simpleDur,
                         int repeatIteration)
Invoked to indicate that this timed element has been sampled at the given time.

Specified by:
sampledAt in class TimedElement
Parameters:
simpleTime - the sample time in local simple time
simpleDur - the simple duration of the element
repeatIteration - the repeat iteration during which the element was sampled

sampledLastValue

protected void sampledLastValue(int repeatIteration)
Invoked to indicate that this timed element has been sampled at the end of its active time, at an integer multiple of the simple duration. This is the "last" value that will be used for filling, which cannot be sampled normally.

Specified by:
sampledLastValue in class TimedElement

getTimedElementById

protected TimedElement getTimedElementById(String id)
Returns the timed element with the given ID.

Specified by:
getTimedElementById in class TimedElement

getEventTargetById

protected EventTarget getEventTargetById(String id)
Returns the event target with the given ID.

Specified by:
getEventTargetById in class TimedElement

getAnimationEventTarget

protected EventTarget getAnimationEventTarget()
Returns the target of this animation as an EventTarget. Used for eventbase timing specifiers where the element ID is omitted.

Specified by:
getAnimationEventTarget in class TimedElement

getRootEventTarget

protected EventTarget getRootEventTarget()
Returns the event target that should be listened to for access key events.

Specified by:
getRootEventTarget in class TimedElement

getElement

public Element getElement()
Returns the DOM element that corresponds to this timed element, if such a DOM element exists.

Specified by:
getElement in class TimedElement

isBefore

public boolean isBefore(TimedElement other)
Returns whether this timed element comes before the given timed element in document order.

Specified by:
isBefore in class TimedElement

currentIntervalWillUpdate

protected void currentIntervalWillUpdate()
Invoked by timed elements in this document to indicate that the current interval will be re-evaluated at the next sample.

Overrides:
currentIntervalWillUpdate in class TimedDocumentRoot
