             Summary: [C++] Add a const overload to MemoryMappedFile::GetSize
                 Key: ARROW-3662
                 URL: https://issues.apache.org/jira/browse/ARROW-3662
             Project: Apache Arrow
          Issue Type: New Feature
    Affects Versions: 0.11.1
            Reporter: Dimitri Vorona


 

While GetSize in general is not a const function, it can be on a MemoryMappedFile. I propose to add a const override directly to the MemoryMappedFile.

Alternatively we could add a const version on the RandomAccessFile level which would fail, if a const size getting (e.g. without a seek) isn't possible, but it seems to me to be a potential source of hard-to-debug bugs and spurious failures. At would at least require a careful analysis of the platform support of different size getting options.
