[dominicc (has gone to gerrit), 2013/12/13 05:11:16]

Let's do the renaming in a follow-up changelist.

I think CustomElementInvocation also needs to be renamed. When processing an
unresolved element, nothing of the author's is getting invoked; "invocation" is
too generic.

Here's a proposal:

CustomElementQueue ("Element Queue" is a spec term)
CustomElementQueueEntry
CustomElementResolveStep : CustomElementQueueEntry
CustomElementUpgradeStep : CustomElementQueueEntry
CustomElementCallbackStep : CustomElementQueueEntry

For now this can be:

CustomElementCallbackQueue
CustomElementQueueEntry
CustomElementResolveStep : CustomElementQueueEntry
CustomElementCallbackInvocation : CustomElementQueueEntry

 class CustomElementCallbackQueue {
     WTF_MAKE_NONCOPYABLE(CustomElementCallbackQueue);
 public:
     static PassOwnPtr<CustomElementCallbackQueue> create(PassRefPtr<Element>);
 
     typedef int ElementQueue;
     ElementQueue owner() { return m_owner; }
     void setOwner(ElementQueue newOwner)
     {
         // ElementCallbackQueues only migrate towards the top of the
         // processing stack.
         ASSERT(newOwner >= m_owner);
         m_owner = newOwner;
     }
 
-    void append(PassOwnPtr<CustomElementCallbackInvocation> invocation) { m_queue.append(invocation); }
+    void append(PassOwnPtr<CustomElementInvocation> invocation) { m_queue.append(invocation); }
     void processInElementQueue(ElementQueue);
     bool inCreatedCallback() const { return m_inCreatedCallback; }
 
 private:
     CustomElementCallbackQueue(PassRefPtr<Element>);
 
     RefPtr<Element> m_element;
-    Vector<OwnPtr<CustomElementCallbackInvocation> > m_queue;
+    Vector<OwnPtr<CustomElementInvocation> > m_queue;
     ElementQueue m_owner;
     size_t m_index;
     bool m_inCreatedCallback;
 };
 
 }
