Description

basic_severity_logger public construct/copy/destruct

  1. basic_severity_logger();

    Default constructor. The constructed logger will have a severity attribute registered. The default level for log records will be 0.

  2. basic_severity_logger(basic_severity_logger const & that);

    Copy constructor

  3. basic_severity_logger(basic_severity_logger && that);

    Move constructor

  4. template<typename ArgsT> explicit basic_severity_logger(ArgsT const & args);

    Constructor with named arguments. Allows to setup the default level for log records.

    Parameters:

    args

    A set of named arguments. The following arguments are supported:

    • severity - default severity value

basic_severity_logger public member functions

  1. severity_level default_severity() const;

    Default severity value getter

basic_severity_logger protected member functions

  1. severity_attribute const  & get_severity_attribute() const;

    Severity attribute accessor

  2. template<typename ArgsT> record open_record_unlocked(ArgsT const & args);

    Unlocked open_record

  3. void swap_unlocked(basic_severity_logger & that);
    Unlocked swap.
