Move IDSet out of windows directory
We need a way to have 32 bit IDs in Android as well. So I propose reusing Windows' IDSet for that. Another thing we need is platform specific implementations of Accessible::UniqueID(). I know that making it virtual comes at a cost, but I don't know if it's a big deal. Would a preprocessor conditional per-platform make more sense? I think we can also fold Windows' GetExistingID into this as well.

Is this so you can just use the ids pushed up from content, rather than pushing up a separate id (like we do on Windows) or generating a separate id in parent? > I know that making it virtual comes at a cost, but I > don't know if it's a big deal. I've never been very good at the memory usage tradeoff question at scale. :) Having said that, it does seem strange to make it virtual when it's never going to be overridden *except* at the platform specific base level. > Would a preprocessor conditional per-platform > make more sense? It'd be more efficient, but I'm trying to imagine how we'd do this without hideous code, since the id generation code for each platform ideally needs to be in the platform specific directory. > I think we can also fold Windows' GetExistingID into this as well. Probably. There are two code paths: one for proxies and one for accessibles originating in this process. However, I imagine that's also true for Android. I need to give this some more thought. Might be worth syncing up on this one.
Comment on attachment 8995253 [details] [diff] [review] Move IDSet out of windows to base for Android use. r?jteh Eitan and I discussed this. Current thinking is to get rid of the virtual and do pre-processor stuff. We'll have a protected mID member which gets set in AccessibleWrap for the platforms which need it. Cancelling review until these changes are made.
We discussed this, and I'll get back with a different patch.
Removed the virtual change. When I introduce the Android dir, i'll put in some preprocessor magic like we discussed.
