zturner added a comment. Actually it looks like `JSONParser` constructor takes a `StringRef` and then converts it to a `std::string` internally. Why can't it just store the `StringRef` internally? It doesn't modify the buffer, and incidentally it also keeps a `uint64_t` representing the "offset" into the string. That's what a `StringRef` is. an immutable buffer and an offset. Each time you extract something, you just say `m_buffer = m_buffer.drop_front(n)`.
There is the `SetFilePos()` method, but it looks like it's only being used for two purposes: 1) To move forward, and 2) To reset the position to 0 after setting a new string in the extractor. The first one is still possible with a `StringRef` by writing `extractor.skip(n)`, and the second one is still possible by writing `extractor.SetString(NewStringRef)`. https://reviews.llvm.org/D23884 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
