Is '&' necessary?

[zentaro, 2016/06/17 23:37:35]

Yes - otherwise is will try to copy which isn't allowed on Array.

+
+ private:
+  friend class base::RefCounted<LocalActivityResolver>;
   ~LocalActivityResolver() = default;
 
-  bool ShouldChromeHandleUrl(const GURL& url);
-
- private:
+  mojo::Array<mojom::IntentFilterPtr> intent_filters_;

Mind adding a code comment to explain what this is?

[zentaro, 2016/06/17 23:37:35]

Done.

   DISALLOW_COPY_AND_ASSIGN(LocalActivityResolver);
