Method: Bio::FlatFile::BufferedInputStream.open_file

Defined in:
lib/bio/io/flatfile/buffer.rb

.open_file(filename, *arg) ⇒ Object

Creates a new input stream wrapper to open file filename by using File.open. *arg is passed to File.open.

Like File.open, a block can be accepted.

Unlike File.open, the default is binary mode, unless text mode is explicity specified in mode.
