C++ (Cpp) validateShadowRoot Examples

Example #1

void ElementShadow::addShadowRoot(Element* shadowHost, PassRefPtr<ShadowRoot> shadowRoot, ShadowRoot::ShadowRootType type, ExceptionCode& ec)
{
    ASSERT(shadowHost);
    ASSERT(shadowRoot);

    if (!validateShadowRoot(shadowHost->document(), shadowRoot.get(), ec))
        return;

    if (type == ShadowRoot::AuthorShadowRoot)
        shadowHost->willAddAuthorShadowRoot();

    shadowRoot->setHost(shadowHost);
    shadowRoot->setParentTreeScope(shadowHost->treeScope());
    m_shadowRoots.push(shadowRoot.get());
    m_distributor.didShadowBoundaryChange(shadowHost);
    ChildNodeInsertionNotifier(shadowHost).notify(shadowRoot.get());

    // Existence of shadow roots requires the host and its children to do traversal using ComposedShadowTreeWalker.
    shadowHost->setNeedsShadowTreeWalker();

    // FIXME(94905): ShadowHost should be reattached during recalcStyle.
    // Set some flag here and recreate shadow hosts' renderer in
    // Element::recalcStyle.
    if (shadowHost->attached())
        shadowHost->lazyReattach();

    InspectorInstrumentation::didPushShadowRoot(shadowHost, shadowRoot.get());
}
