You don't save a copy by doing this--you still end up copying the contents of
the WebVector by calling this function.

Since this function is only needed by DataObject, that's why I suggested
friending it and just having it swap the items directly.

//content/renderer/render_view_impl.cc also uses setItems.
Since the code uses std::vector<WebDragData::Item>, I cannot use
WebVector<Item>& here.

So I added setItemsFast for blink. I will fix render_view_impl.cc later.

Ah, I forgot about that.

Maybe just call it swapItems(), since that's what it does.

 {
+    ASSERT(!isNull());
+    m_itemList.swap(itemList);
 }
 
-WebURL& WebURL::operator=(const KURL& url)
+void WebDragData::addItem(const Item& item)
 {
-    m_string = url.string();
-    m_parsed = url.parsed();
-    m_isValid = url.isValid();
-    return *this;
-}
+    ASSERT(!isNull());
+    WebVector<Item> itemList(m_itemList.size() + 1);
 
-WebURL::operator KURL() const
-{
-    return KURL(m_string, m_parsed, m_isValid);
+    for (unsigned i = 0; i < m_itemList.size(); ++i)
+        itemList[i] = m_itemList[i];
+    itemList[m_itemList.size()] = item;
+    m_itemList.swap(itemList);
 }
