示例1: removeEventListenersForTarget
void EventDispatcher::removeEventListenersForTarget(Node* target, bool recursive/* = false */)
{
// Ensure the node is removed from these immediately also.
// Don't want any dangling pointers or the possibility of dealing with deleted objects..
_nodePriorityMap.erase(target);
_dirtyNodes.erase(target);
auto listenerIter = _nodeListenersMap.find(target);
if (listenerIter != _nodeListenersMap.end())
{
auto listeners = listenerIter->second;
auto listenersCopy = *listeners;
for (auto& l : listenersCopy)
{
removeEventListener(l);
}
}
// Bug fix: ensure there are no references to the node in the list of listeners to be added.
// If we find any listeners associated with the destroyed node in this list then remove them.
// This is to catch the scenario where the node gets destroyed before it's listener
// is added into the event dispatcher fully. This could happen if a node registers a listener
// and gets destroyed while we are dispatching an event (touch etc.)
for (auto iter = _toAddedListeners.begin(); iter != _toAddedListeners.end(); )
{
EventListener * listener = *iter;
if (listener->getAssociatedNode() == target)
{
listener->setAssociatedNode(nullptr); // Ensure no dangling ptr to the target node.
listener->setRegistered(false);
releaseListener(listener);
iter = _toAddedListeners.erase(iter);
}
else
{
++iter;
}
}
if (recursive)
{
const auto& children = target->getChildren();
for (const auto& child : children)
{
removeEventListenersForTarget(child, true);
}
}
