virtual ~QueryTokenizer()
destruct an instance of this class.
bool valid() const
can be used to check if analyzing of given query was successful or not.
QueryTokenizer(std::u16string_view sQuery)
create a new tokenizer instance with a a new query.
bool m_bValid
Because the given query can contain errors, it should be checked outside.
