[webkit-dev] Naming scheme for fooIfExists/ensureFoo - Round 2

[Ryosuke Niwa]

Hi all,

We discussed this topic 11 years ago in https://lists.webkit.org/pipermail/webkit-dev/2013-June/025056.html but we seem to have never codified it in our coding style guideline. It really bothers me that we have a mixture of two styles so I’d like to propose that we pick one style and put that into style guideline & style checker.

The question is as follows. A pair of functions which lazily construct an object and one which returns nullptr if the object had not already been constructed can be named:

StyleResolver* styleResolver();
StyleResolver& ensureStyleResolver();

or:

StyleResolver* styleResolverIfExists();
StyleResolver& styleResolver();

Which one should we use?
