Class Method Details

.parse(io, ignore_count: true) ⇒ Object

Parse given IO for meta data. Reads from +io+ until a "# End of header" line is found (enhancing its pos). By default, ignores reading the count (indecating the amount of datasets in the file) because it is written at the end of the file.
