Subject: Per code review:
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=b608a81a18dee7fbae18147f10af3fd1db31a5f4;p=oota-llvm.git

Per code review:
* Clean up the StatusInfo constructor to construct all members and give
  them reasonable values.
* Get rid of the Vector typedef and make the interface to
  getDirectoryContent use a std::set instead of a std::vector so the dir
  content is sorted.
* Make the getStatusInfo method const and not return a useless boolean.
