Function Documentation

std::vector<std::string> StringUtils::split	(	const std::string &	s,
		char	delimiter,
		bool	removeEmpty = false,
		unsigned int	limit = 0
	)

Split a string at a given separator.

std::string StringUtils::trim

(

std::string const &

str

)

Remove leading and trailing spaces from a string.

long long int StringUtils::parseAsInt

(

std::string const &

str

)

Parses a string as a decimal or hex integer

std::vector<char*> StringUtils::makeArgv

(

std::vector< std::string > &

strings

)

Turns a vector of strings into a vector of char*, useful for generating argv, with the first element being a nullptr. Note: the pointers are not const char*, because this is the way argv normally is. However, I don't think getopt_long() and the likes actually change the content of the memory locations.

Parameters

strings

the vector of strings.

Returns

a vector of const char*. Each element points to the memory allocated by each of the elements of strings, and is therefore only valid as long as the latter remains unchanged.
