Please rename to PushRegistrationCallbacks. It's an awful name but I'd like to
be consistent with the WebCallbacks it inherits from.

[mlamouri (slow - plz ping), 2014/12/15 10:55:07]

Sic :(

+    : public WebCallbacks<WebPushRegistration, WebPushError> {

[Michael van Ouwerkerk, 2014/12/12 12:18:04]

Just write WebPushRegistrationCallbacks

[jochen (gone - plz use gerrit), 2014/12/12 14:26:12]

should be on previous line (no line length limit)

[mlamouri (slow - plz ping), 2014/12/15 10:55:07]

Hmm, I don't think so. It would require including WebPushProvider.h to get the
typedef.

+public:
+    explicit PushRegistrationCallback(PassRefPtr<ScriptPromiseResolver>, ServiceWorkerRegistration*);

[Michael van Ouwerkerk, 2014/12/12 12:18:04]

omit explicit as there are two arguments

[mlamouri (slow - plz ping), 2014/12/15 10:55:07]

Done.

+    virtual ~PushRegistrationCallback();

[Michael van Ouwerkerk, 2014/12/12 12:18:04]

Hmmz, I guess we should mark these with override instead of virtual.

[mlamouri (slow - plz ping), 2014/12/15 10:55:07]

Done.

+
+    void onSuccess(WebPushRegistration*) override;
+    void onError(WebPushError*) override;
+
+    void trace(Visitor*);
+
+private:
+    RefPtr<ScriptPromiseResolver> m_resolver;
+    Persistent<ServiceWorkerRegistration> m_registration;

[Michael van Ouwerkerk, 2014/12/12 12:18:04]

Please rename to m_serviceWorkerRegistration to distinguish from that other
registration.

[mlamouri (slow - plz ping), 2014/12/15 10:55:07]

Done.
