Inherits:
RangesIO show all
Defined in:
lib/ole/ranges_io.rb

Overview

this subclass of ranges io explicitly ignores the truncate part of ‘w’ modes. only really needed for the allocation table writes etc. maybe just use explicit modes for those better yet write a test that breaks before I fix it. added nodoc for the time being.
