source: branches/0.9-stable/lib/ClassicStats.cc @ 1276

Last change on this file since 1276 was 1276, checked in by Peter Johansson, 12 years ago

Let Graph class hold information about last point (rev_max_) rather
than defining via the size of Vector. Not resizing the Vectors means
we can avoid some copying in Stats class. But it also means we need to
handle the case of empty Vector in Stats::max_element. Made the
function Node::svn_info(void) public. In svndigest.cc set rev_min also
when not using dates as well as setting the new static variable rev_max.
closes #485

  • Property svn:eol-style set to native
  • Property svn:keywords set to Id
