      • trace

        void trace​(String msg)
        Log a message at the TRACE level.
        Parameters:
        msg - the message string to be logged

      • trace

        void trace​(String format,
           Object arg)
        Log a message at the TRACE level according to the specified format and argument.

        This form avoids superfluous object creation when the logger is disabled for the TRACE level.

        Parameters:
        format - the format string
        arg - the argument

      • trace

        void trace​(String format,
           Object argA,
           Object argB)
        Log a message at the TRACE level according to the specified format and arguments.

        This form avoids superfluous object creation when the logger is disabled for the TRACE level.

        Parameters:
