Memory-mapped sub-data?

If I take a "subdata" of a memory-mapped (NS)Data, does it stay mapped (i.e. use a range and reference)? Or does a full copy get made? I'm thinking of making a parser be a sub-parser too, and this would make the difference between scanning the next megabyte or the rest-of-file (even if it's gigabytes).
