Bug 112857 – AXObjectCache::postNotification should use an enum instead of a bool

• Component: Accessibility
• Status: RESOLVED DUPLICATE

AXObjectCache::postNotification should use an enum instead of a bool (since it's a multi-argument function)

I'm slowly trying to rid WebKit of this pattern, as it leads to very difficult to understand callsites:
    axObjectCache()->postNotification(node(), AXObjectCache::AXValueChanged, true);

At least:
    axObjectCache()->postNotification(node(), AXObjectCache::AXValueChanged, PostToElement);

would be clearer.  Although it's not yet clear to me what the "postToElement" bool is supposed to do. :)

Once I figure out what postToElement means, I can come up with nice names for a replacement enum.  Any suggestions would be most welcome. :)

I was given this same feedback (we should not use a bool) in response to another patch that I landed. I fixed this issue under:

https://bugs.webkit.org/show_bug.cgi?id=121504

before I saw this bug. Apologies.

Marking as dupe, but note that this bug was filed first. Not sure if there's a better way to indicate that. Thanks!
