std::string str_no_whitespace | ( | ) | const |
returns a new string with all whitespace removed from this StringRef
StringRef substr | ( | size_t | pos, | |
size_t | n = std::string::npos | |||
) | const [inline] |
returns a substring of the string
pos | the starting position of the substring | |
n | is the length of the string. if std::string::npos, the substring goes from pos to the end of the string The function does on purpose not perform any boundary check in release mode. It's the duty of the caller to make sure the string has the required length. |

convert to float
first
set to true and second
set to the float if the conversion succeeds. If the conversion fails, first
is set to false. std::pair<bool, int> to_int | ( | ) | const |
convert to integer
first
set to true and second
set to the int if the conversion succeeds. If the conversion fails, first
is set to false. StringRef trim | ( | ) | const [inline] |
strip space characters on the left and the right
