Examples of java.util.logging.Formatter

java.util.logging.Formatter
A Formatter provides support for formatting LogRecords.
Typically each logging Handler will have a Formatter associated with it. The Formatter takes a LogRecord and converts it to a string.
Some formatters (such as the XMLFormatter) need to wrap head and tail strings around a set of formatted records. The getHeader and getTail methods can be used to obtain these strings. @version 1.17, 11/17/05 @since 1.4

            // the formatter.format will fail with NullPointerException (#12588)
            if (record.getMessage() == null) {
                record.setMessage("");
            }


            Formatter formatter = getFormatter();
            String msg = formatter.format(record);


            addRow(record.getLevel(), msg);
        }
