Last change on this file since 6634 was 6394, checked in by rgrieder, 15 years ago

std::string tweaks:

  • Declared BLANKSTRING in UtilPrereqs.h as well (removed obsolete StringUtils.h includes to avoid dependencies)
  • Using BLANKSTRING if const std::string& return type is possible
  • Replaced a few (const) std::string arguments with const std::string&
  • if (str == "") —> if (str.empty())
  • std::string msg = name + "adsf"; —> const std::string& msg = name + "asdf";
  • std::string asdf = object→getFooBar(); —> const std::string& asdf = object→getFooBar();
  • std::string asdf = "asdf"; —> std::string asdf("asdf");
  • ostream << "."; and name + "." —> ostream << '.'; and name + '.'
  • str = ""; —> str.clear()
  • std::string asdf = ""; —> std::string asdf;
  • asdf_ = ""; (in c'tor) —> delete line
  • Property svn:eol-style set to native
