aren't modules already on oilpan, so you don't need WillBe types anymore?

[Marijn Kruisselbrink, 2015/05/18 18:29:35]

But StashedMessagePort inherits from MessagePort, which is still refcounted. So
unfortunately still need WillBe types.

+
+// Represents a message port that has been stashed. Overrides messageAvailable
+// to dispatch messages as a global event instead of as events on this port.
+class StashedMessagePort final
+    : public MessagePort {

no explicit, should also come before other private methods
