There is often a lot of boilerplate code required to visit a type record or type stream. The #1 use case is that you have a sequence of bytes that represent one or more records, and you want to deserialize each one, switch on it, and call a callback with the deserialized record that the user can examine. Currently this requires at least 6 lines of code: codeview::TypeVisitorCallbackPipeline Pipeline; Pipeline.addCallbackToPipeline(Deserializer); Pipeline.addCallbackToPipeline(MyCallbacks); codeview::CVTypeVisitor Visitor(Pipeline); consumeError(Visitor.visitTypeRecord(Record)); With this patch, it becomes one line of code: consumeError(codeview::visitTypeRecord(Record, MyCallbacks)); This is done by having the deserialization happen internally inside of the visitTypeRecord function. Since this is occasionally not desirable, the function provides a 3rd parameter that can be used to change this behavior. Hopefully this can significantly reduce the barrier to entry to using the visitation infrastructure. Differential Revision: https://reviews.llvm.org/D33245 llvm-svn: 303271 |
