示例1: makeCounterNode
static CounterNode* makeCounterNode(RenderObject* object, const AtomicString& identifier, bool alwaysCreateCounter)
{
ASSERT(object);
// Real text nodes don't have their own style so they can't have counters.
// We can't even look at their styles or we'll see extra resets and increments!
if (object->isText())
return nullptr;
RenderElement* element = toRenderElement(object);
if (element->hasCounterNodeMap()) {
if (CounterMap* nodeMap = counterMaps().get(element)) {
if (CounterNode* node = nodeMap->get(identifier))
return node;
}
}
bool isReset = false;
int value = 0;
if (!planCounter(element, identifier, isReset, value) && !alwaysCreateCounter)
return nullptr;
RefPtr<CounterNode> newParent = 0;
RefPtr<CounterNode> newPreviousSibling = 0;
RefPtr<CounterNode> newNode = CounterNode::create(element, isReset, value);
if (findPlaceForCounter(element, identifier, isReset, newParent, newPreviousSibling))
newParent->insertAfter(newNode.get(), newPreviousSibling.get(), identifier);
CounterMap* nodeMap;
if (element->hasCounterNodeMap())

element->setHasCounterNodeMap(true);
}
nodeMap->set(identifier, newNode);
if (newNode->parent())
return newNode.get();
// Checking if some nodes that were previously counter tree root nodes
// should become children of this node now.
CounterMaps& maps = counterMaps();
Element* stayWithin = parentOrPseudoHostElement(element);
bool skipDescendants;

break;

}
return newNode.get();
}
示例2: destroyCounterNodes
void RenderCounter::destroyCounterNodes(RenderElement& owner)
{
CounterMaps& maps = counterMaps();
CounterMaps::iterator mapsIterator = maps.find(&owner);
if (mapsIterator == maps.end())
return;
CounterMap* map = mapsIterator->value.get();

for (CounterMap::const_iterator it = map->begin(); it != end; ++it) {
destroyCounterNodeWithoutMapRemoval(it->key, it->value.get());
}
maps.remove(mapsIterator);
owner.setHasCounterNodeMap(false);
}
