Detailed Description

convenient datatype for referencing character data

Note
it is not in general safe to store a StringRef as it does not guarantee that the character data it points to stays alive.

split string into chunks delimited by whitespace

std::string str ( ) const
inline

Definition at line 94 of file string_ref.hh.

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

Parameters
posthe starting position of the substring
nis 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.

Definition at line 84 of file string_ref.hh.

std::pair<bool, float> to_float ( ) const

convert to float

Returns
a tuple with 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

Returns
a tuple with 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
