Function ReferTo

3rdparty/flatbuffers/include/flatbuffers/flatbuffers.h:710–716

Offsets initially are relative to the end of the buffer (downwards). This function converts them to be relative to the current location in the buffer (when stored here), pointing upwards.

  // This function converts them to be relative to the current location
  // in the buffer (when stored here), pointing upwards.
  uoffset_t ReferTo(uoffset_t off) {
    // Align to ensure GetSize() below is correct.
    Align(sizeof(uoffset_t));
    // Offset must refer to something already in buffer.
    assert(off && off <= GetSize());
    return GetSize() - off + sizeof(uoffset_t);
  }
