| -// How ownership works
|
| -// -------------------
|
| -//
|
| -// Big oh represents a refcounted relationship: owner O--- ownee
|
| -//
|
| -// WebView (for the toplevel frame only)
|
| -// O
|
| -// |
|
| -// Page O------- Frame (m_mainFrame) O-------O FrameView
|
| -// ||
|
| -// ||
|
| -// FrameLoader O-------- WebFrame (via FrameLoaderClient)
|
| -//
|
| -// FrameLoader and Frame are formerly one object that was split apart because
|
| -// it got too big. They basically have the same lifetime, hence the double line.
|
| -//
|
| -// WebFrame is refcounted and has one ref on behalf of the FrameLoader/Frame.
|
| -// This is not a normal reference counted pointer because that would require
|
| -// changing WebKit code that we don't control. Instead, it is created with this
|
| -// ref initially and it is removed when the FrameLoader is getting destroyed.
|
| -//
|
| -// WebFrames are created in two places, first in WebViewImpl when the root
|
| -// frame is created, and second in WebFrame::createChildFrame when sub-frames
|
| -// are created. WebKit will hook up this object to the FrameLoader/Frame
|
| -// and the refcount will be correct.
|
| -//
|
| -// 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 FrameLoader::detachFromParent for each subframe.
|
| -//
|
| -// Frame going away causes the FrameLoader to get deleted. In FrameLoader's
|
| -// destructor, it notifies its client with frameLoaderDestroyed. This derefs
|
| -// the WebFrame and will cause it to be deleted (unless an external someone
|
| -// is also holding a reference).
|
| -//
|
| -// Thie client is expected to be set whenever the WebFrameImpl is attached to
|
| -// the DOM.
