示例1: startHighlightAnimationIfNeeded

void LinkHighlight::startHighlightAnimationIfNeeded()
{
    if (m_isAnimating)
        return;

    m_isAnimating = true;
    const float startOpacity = 1;
    // FIXME: Should duration be configurable?
    const float fadeDuration = 0.1f;
    const float minPreFadeDuration = 0.1f;

    m_contentLayer->layer()->setOpacity(startOpacity);

    WebCompositorSupport* compositorSupport = Platform::current()->compositorSupport();

    OwnPtr<WebFloatAnimationCurve> curve = adoptPtr(compositorSupport->createFloatAnimationCurve());

    curve->add(WebFloatKeyframe(0, startOpacity));
    // Make sure we have displayed for at least minPreFadeDuration before starting to fade out.
    float extraDurationRequired = std::max(0.f, minPreFadeDuration - static_cast<float>(monotonicallyIncreasingTime() - m_startTime));
    if (extraDurationRequired)
        curve->add(WebFloatKeyframe(extraDurationRequired, startOpacity));
    // For layout tests we don't fade out.
    curve->add(WebFloatKeyframe(fadeDuration + extraDurationRequired, blink::layoutTestMode() ? startOpacity : 0));

    OwnPtr<WebAnimation> animation = adoptPtr(compositorSupport->createAnimation(*curve, WebAnimation::TargetPropertyOpacity));

    m_contentLayer->layer()->setDrawsContent(true);
    m_contentLayer->layer()->addAnimation(animation.leakPtr());

    invalidate();
