virtual?

[Bernhard Bauer, 2012/08/14 15:36:57]

This class is never destructed via a superclass, so a virtual destructor isn't
necessary. It also doesn't have any virtual methods yet, so making the
destructor virtual would add a vtable to the class, for no benefit.

+  // Returns true if the URL is matched by the filter.
+  bool IsURLWhitelisted(const GURL& url) const;
+
+  // Sets whether the filter is active or not. If the filter is inactive, it
+  // won't match any URL.

nit: add comment that this is inactive by default?

[battre, 2012/08/14 11:58:33]

What does it mean "it won't match any URLs"? -> maybe "it reports all URLs as
whitelisted"?

[Bernhard Bauer, 2012/08/14 15:36:57]

Done.

[Bernhard Bauer, 2012/08/14 15:36:57]

Done.
