Maybe this file should be in page? What other classes is this expected to vend?

[slangley, 2017/05/17 04:39:44]

We'll use this class to construct many of the web/*Impl classes
(WebLocalFrameImpl, WebPluginContainerImpl, ChromeClientImpl) etc etc.

Yeah, where do you think this file belongs? I was thinking core/exported even.

+
+#include "core/CoreExport.h"
+#include "public/platform/WebPageVisibilityState.h"
+
+namespace blink {
+
+class ChromeClient;
+class WebViewBase;
+class WebViewClient;
+
+// WebFactory is a temporary class implemented in web/ that allows classes to
+// construct interfaces that are being moved out of web/.
+// This class will be removed once all implementations are in core/ or modules/.
+class CORE_EXPORT WebFactory {
+ public:
+  // Takes ownership of |factory|.
+  CORE_EXPORT static void SetInstance(WebFactory*);

[slangley, 2017/05/17 04:39:44]

not sure if you need these additional CORE_EXPORT if the class is already
CORE_EXPORT.

[sashab, 2017/05/22 03:45:05]

Removed.

+  CORE_EXPORT static WebFactory& GetInstance();
+
+  virtual ChromeClient* CreateChromeClient(WebViewBase*) const = 0;
+  virtual WebViewBase* CreateWebViewBase(WebViewClient*,
+                                         WebPageVisibilityState) const = 0;
+
+ private:
+  static WebFactory* factory_instance_;
+};

Nit: newline for consistency

Done for both
