// How ownership works
// -------------------
//
// Big oh represents a refcounted relationship: owner O--- ownee
//
// WebView (for the toplevel frame only)
// O
// | WebFrame
// | O
// | |
// Page O------- LocalFrame (main_frame_) O-------O LocalFrameView
// ||
// ||
// FrameLoader
//
// FrameLoader and LocalFrame are formerly one object that was split apart
// because it got too big. They basically have the same lifetime, hence the
// double line.
//
// From the perspective of the embedder, WebFrame is simply an object that it
// allocates by calling WebFrame::create() and must be freed by calling close().
// Internally, WebFrame is actually refcounted and it holds a reference to its
// corresponding LocalFrame in blink.
//
// Oilpan: the middle objects + Page in the above diagram are Oilpan heap
// allocated, WebView and LocalFrameView are currently not. In terms of
// ownership and control, the relationships stays the same, but the references
// from the off-heap WebView to the on-heap Page is handled by a Persistent<>,
// not a scoped_refptr<>. Similarly, the mutual strong references between the
// on-heap LocalFrame and the off-heap LocalFrameView is through a RefPtr (from
// LocalFrame to LocalFrameView), and a Persistent refers to the LocalFrame in
// the other direction.
//
// From the embedder's point of view, the use of Oilpan brings no changes.
// close() must still be used to signal that the embedder is through with the
// WebFrame. Calling it will bring about the release and finalization of the
// frame object, and everything underneath.
//
// How frames are destroyed
// ------------------------
//
// The main frame is never destroyed and is re-used. The FrameLoader is re-used
// and a reference to the main frame is kept by the Page.
//
// When frame content is replaced, all subframes are destroyed. This happens
// in Frame::detachChildren for each subframe in a pre-order depth-first
// traversal. Note that child node order may not match DOM node order!
// detachChildren() (virtually) calls Frame::detach(), which again calls
// LocalFrameClient::detached(). This triggers WebFrame to clear its reference
// to LocalFrame. LocalFrameClient::detached() also notifies the embedder via
// WebLocalFrameClient that the frame is detached. Most embedders will invoke
// close() on the WebFrame at this point, triggering its deletion unless
// something else is still retaining a reference.
//
// The client is expected to be set whenever the WebLocalFrameImpl is attached
// to the DOM.
