Description

An adapter class that allows to use regular formatters as file name generators.

file_name_composer_adapter public construct/copy/destruct

  1. explicit file_name_composer_adapter(formatter_type const & formatter, 
                                        std::locale const & loc = std::locale());

    Initializing constructor

  2. file_name_composer_adapter(file_name_composer_adapter const & that);

    Copy constructor

  3. file_name_composer_adapter& operator=(file_name_composer_adapter const & that);

    Assignment

file_name_composer_adapter public member functions

  1. result_type operator()(record_view const & rec) const;
