If we have a creator parser, then we were a parser-inserted script and should
presumably be able to set a valid insertion point when we run or fire our
load/error events. For the error event case, we do this in
nsScriptElement::ScriptAvailable, so that async error events due to things like
bogus script URLs do not end up with a valid insertion point. For the load
event case, we just do this in ScriptEvaluated directly.
ScriptEvaluated is called while the scriptloader has our script set as the
current parser-inserted script. But for the error event case we need to
maintain that state around the ScriptAvailable call that will fire the event.
This patch makes the following changes on many in-class methods.
- NS_IMETHODIMP F() override; --> NS_IMETHOD F() override;
- NS_IMETHODIMP F() override {...} --> NS_IMETHOD F() override {...}
- NS_IMETHODIMP F() final; --> NS_IMETHOD F() final;
- NS_IMETHODIMP F() final {...} --> NS_IMETHOD F() final {...}
Using NS_IMETHOD is the preferred way of marking in-class virtual methods.
Although these transformations add an explicit |virtual|, they are safe --
there's an implicit |virtual| anyway because |override| and |final| only work
with virtual methods.
