Description |
If no arguments are passed, this command will return a list containing the type (e.g [#lower, #alpha, #alphanum]) of strX.
If #prop is passed, the result will be a propList containing flag:boolean pairs, for all flags.
If one or more flags are passed, the Xtra will return true if the string's content qualifies for all flags, or false otherwise.
If an invalid argument is passed, or an error occurs, an <err> will be returned.
