Changeset 6394 for code/branches/presentation2/src/libraries/core/input

Timestamp:

Dec 22, 2009, 2:07:44 PM (15 years ago)

Author:

Message:

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
