示例1:
AnimationPlayerCollection*
CommonAnimationManager::GetAnimationsForCompositor(nsIContent* aContent,
nsIAtom* aElementProperty,
nsCSSProperty aProperty)
{
if (!aContent->MayHaveAnimations())
return nullptr;
AnimationPlayerCollection* collection =
static_cast<AnimationPlayerCollection*>(
aContent->GetProperty(aElementProperty));
if (!collection ||
!collection->HasAnimationOfProperty(aProperty) ||
!collection->CanPerformOnCompositorThread(
AnimationPlayerCollection::CanAnimate_AllowPartial)) {
return nullptr;
}
// This animation can be done on the compositor.
return collection;
}示例2: mb

// in its "done" state, and if there isn't, remove ourselves from
// the refresh driver (but leave the animations!).
