Do you actually need a create method that takes a type but no Init dictionary?
Other events with similar constructor signature seem to be able to get away with
only having a create() and a create(type, init) method.

[please use gerrit instead, 2016/05/03 21:38:33]

Done.

+    static PaymentRequestUpdateEvent* create(const AtomicString& type, const PaymentRequestUpdateEventInit&);
+
+    void setPaymentDetailsUpdater(PaymentUpdater*);
+
+    void updateWith(ScriptState*, ScriptPromise);
+
+    DECLARE_VIRTUAL_TRACE();
+
+private:
+    PaymentRequestUpdateEvent();
+    explicit PaymentRequestUpdateEvent(const AtomicString& type);
+
+    Member<PaymentUpdater> m_updater;
+};
+
+} // namespace blink
