## Class template basic_settings

boost::log::basic_settings — The class represents settings container.

## Synopsis

    // In header: <boost/log/utility/setup/settings.hpp>

    template<typename CharT>
    class basic_settings : public boost::log::basic_settings_section< CharT > {
    public:
      // types
      typedef basic_settings_section< CharT > section;             // Section type.
      typedef section::property_tree_type     property_tree_type;  // Property tree type.

      // construct/copy/destruct
      basic_settings();
      basic_settings(basic_settings const &);
      basic_settings(this_type &&);
      explicit basic_settings(property_tree_type const &);
      basic_settings & operator=(basic_settings const &);
      basic_settings & operator=(basic_settings &&);
      ~basic_settings();
    };

## Description

All settings are presented as a number of named parameters divided into named sections. The parameters values are stored as strings. Individual parameters may be queried via subscript operators, like this:

`<preformatted> optional< string > param = settings["Section1"]["Param1"]; // reads parameter "Param1" in section "Section1" // returns an empty value if no such parameter exists settings["Section2"]["Param2"] = 10; // sets the parameter "Param2" in section "Section2" // to value "10" </preformatted>`

There are also other methods to work with parameters.
