In PicnicSupermarket/error-prone-support#261 we're developing an approach to speed up Refaster. The idea is to first index all identifiers referenced by Refaster
@BeforeTemplates and then use the identifiers found in a compilation unit under consideration to select the subset of Refaster rules that have a nonzero probability of matching.While working on this, we noticed that
UAnyOf#accept(TreeVisitor, Object)descends only into the first expression passed toRefaster#anyOf. This PR proposes thatTreeVisitor#visitOtheris invoked instead. This allows the visitor to implement proper support forUAnyOfif desired. With this change, all public Error Prone unit tests still pass. We hope that this change is also compatible with Google-internal code. Naturally, we are open to alternatives that would allow visiting allUAnyOfsubtrees.In the context of this same project, we have another question regarding some non-public types and methods of the Refaster implementation. Currently, we're using reflection to access some of these. Ideally, we avoid this approach. Would you be open to increasing the visibility of certain types and methods?
