示例1: findHostChildWithSameSlotName
bool HTMLSlotElement::findHostChildWithSameSlotName() const {
ShadowRoot* root = containingShadowRoot();
DCHECK(root);
DCHECK(root->isV1());
SlotAssignment& assignment = root->ensureSlotAssignment();
return assignment.findHostChildBySlotName(name());
}示例2: removedFrom
void HTMLSlotElement::removedFrom(ContainerNode* insertionPoint) {
// `removedFrom` is called after the node is removed from the tree.
// That means:
// 1. If this slot is still in a tree scope, it means the slot has been in a
// shadow tree. An inclusive shadow-including ancestor of the shadow host was
// originally removed from its parent.
// 2. Or (this slot is now not in a tree scope), this slot's inclusive
// ancestor was orginally removed from its parent (== insertion point). This
// slot and the originally removed node was in the same tree.
ShadowRoot* root = containingShadowRootBeforeRemoved(*this, *insertionPoint);
if (root) {
if (ElementShadow* rootOwner = root->owner())
rootOwner->setNeedsDistributionRecalc();
}
// Since this insertion point is no longer visible from the shadow subtree, it
// need to clean itself up.
clearDistribution();
if (root && root->isV1() && root == insertionPoint->treeScope().rootNode()) {
// This slot was in a shadow tree and got disconnected from the shadow root.
root->ensureSlotAssignment().slotRemoved(*this);
}
HTMLElement::removedFrom(insertionPoint);
}示例3: hasAssignedNodesSlow
bool HTMLSlotElement::hasAssignedNodesSlow() const {
ShadowRoot* root = containingShadowRoot();
DCHECK(root);
DCHECK(root->isV1());
SlotAssignment& assignment = root->ensureSlotAssignment();
if (assignment.findSlotByName(name()) != this)
return false;
return assignment.findHostChildBySlotName(name());
}示例4: insertedInto
Node::InsertionNotificationRequest HTMLSlotElement::insertedInto(
ContainerNode* insertionPoint) {
HTMLElement::insertedInto(insertionPoint);
ShadowRoot* root = containingShadowRoot();
if (root) {
DCHECK(root->owner());
root->owner()->setNeedsDistributionRecalc();
// Relevant DOM Standard: https://dom.spec.whatwg.org/#concept-node-insert
// - 6.4: Run assign slotables for a tree with node's tree and a set
// containing each inclusive descendant of node that is a slot.
if (root->isV1() && !wasInShadowTreeBeforeInserted(*this, *insertionPoint))
root->ensureSlotAssignment().slotAdded(*this);
}
// We could have been distributed into in a detached subtree, make sure to
// clear the distribution when inserted again to avoid cycles.
clearDistribution();
return InsertionDone;
