示例1: GetRenderedDocument
bool
Animation::IsPossiblyOrphanedPendingAnimation() const
{
// Check if we are pending but might never start because we are not being
// tracked.
//
// This covers the following cases:
//
// * We started playing but our effect's target element was orphaned
// or bound to a different document.
// (note that for the case of our effect changing we should handle
// that in SetEffect)
// * We started playing but our timeline became inactive.
// In this case the pending animation tracker will drop us from its hashmap
// when we have been painted.
// * When we started playing we couldn't find a PendingAnimationTracker to
// register with (perhaps the effect had no document) so we simply
// set mPendingState in DoPlay and relied on this method to catch us on the
// next tick.
// If we're not pending we're ok.
if (mPendingState == PendingState::NotPending) {
return false;
}
// If we have a pending ready time then we will be started on the next
// tick.
if (!mPendingReadyTime.IsNull()) {
return false;
}
// If we don't have an active timeline then we shouldn't start until
// we do.
if (!mTimeline || mTimeline->GetCurrentTime().IsNull()) {
return false;
}
// If we have no rendered document, or we're not in our rendered document's
// PendingAnimationTracker then there's a good chance no one is tracking us.
//
// If we're wrong and another document is tracking us then, at worst, we'll
// simply start/pause the animation one tick too soon. That's better than
// never starting/pausing the animation and is unlikely.
nsIDocument* doc = GetRenderedDocument();
if (!doc) {
return false;
}
PendingAnimationTracker* tracker = doc->GetPendingAnimationTracker();
return !tracker ||
(!tracker->IsWaitingToPlay(*this) &&
!tracker->IsWaitingToPause(*this));
