A simple tokenizer that splits a string into tokens, which are separated by separator characters. An iterator is used to iterate over all tokens.

Member Summary

Member Functions: begin, count, end, operator

Types

Iterator

typedef std::vector < std::string >::const_iterator Iterator;

Enumerations

Options

TOK_IGNORE_EMPTY = 1

ignore empty tokens

TOK_TRIM = 2

remove leading and trailing whitespace from tokens

Constructors

StringTokenizer

StringTokenizer(
    const std::string & str,
    const std::string & separators,
    int options = 0
);

Splits the given string into tokens. The tokens are expected to be separated by one of the separator characters given in separators. Additionally, options can be specified:

An empty token at the end of str is always ignored. For example, a StringTokenizer with the following arguments:

StringTokenizer(",ab,cd,", ",");

will produce three tokens, "", "ab" and "cd".

Destructor

~StringTokenizer

~StringTokenizer();

Destroys the tokenizer.

const std::string & operator[] (
    std::size_t index
) const;
