open() virtual void open ( const std::string &  filename, FileMode  permission  ) privatevirtual Open a FITS file with given filename and permission. This method can only be used after having closed the file; It throws an exception otherwise. This method can be used to change the permission: FitsFile f(filename, FileMode::Create); ... // Write things f.close(); f.open(filename, FileMode::Read); ... // Read things ... but not to change the filename: If called with another filename, another FITS file will be opened. Warning In any case, relying on the constructors and destructors by managing the object lifetime is preferable.
