Add final.

[jrummell, 2014/10/24 22:43:22]

Done.

You can remove ConvertDictionaryIntoMediaKeySystemOptions.

MediaKeySystemOptions impl;
V8MediaKeySystemOptions::toImpl(isolate, value, impl, exceptionState);
return impl;

You will need to include "bindings/modules/v8/V8MediaKeySystemOptions.h".

Great. It even does the enum value checking.

+        return ConvertDictionaryIntoMediaKeySystemOptions(dictionary, exceptionState);
+    }
+};
+
+} // namespace blink

+#endif // NavigatorRequestMediaKeySystemAccess_h
