jdk.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.

formatclj
(format this record)Format the given log record and return the formatted string.
The resulting formatted String will normally include a localized and formatted version of the LogRecord's message field. It is recommended to use the formatMessage(java.util.logging.LogRecord) convenience method to localize and format the message field.
record - the log record to be formatted. - java.util.logging.LogRecord
returns: the formatted log record - java.lang.String

It is recommended to use the formatMessage(java.util.logging.LogRecord) convenience method to localize and format the message field. record - the log record to be formatted. - `java.util.logging.LogRecord` returns: the formatted log record - `java.lang.String`
format-messageclj
(format-message this record)Localize and format the message string from a log record. This method is provided as a convenience for Formatter subclasses to use when they are performing formatting.
The message string is first localized to a format string using the record's ResourceBundle. (If there is no ResourceBundle, or if the message key is not found, then the key is used as the format string.) The format String uses java.text style formatting.
If there are no parameters, no formatter is used. Otherwise, if the string contains "{0" then java.text.MessageFormat is used to format the string. Otherwise no formatting is performed.
record - the log record containing the raw message - java.util.logging.LogRecord

record - the log record containing the raw message - `java.util.logging.LogRecord`
returns: a localized and formatted message - `java.lang.String`get-headclj
(get-head this h)Return the header string for a set of formatted records.
This base class returns an empty string, but this may be overridden by subclasses.
h - The target handler (can be null) - java.util.logging.Handler
returns: header string - java.lang.String
Return the header string for a set of formatted records. This base class returns an empty string, but this may be overridden by subclasses. h - The target handler (can be null) - `java.util.logging.Handler` returns: header string - `java.lang.String`
get-tailclj
(get-tail this h)Return the tail string for a set of formatted records.
This base class returns an empty string, but this may be overridden by subclasses.
h - The target handler (can be null) - java.util.logging.Handler
returns: tail string - java.lang.String
Return the tail string for a set of formatted records. This base class returns an empty string, but this may be overridden by subclasses. h - The target handler (can be null) - `java.util.logging.Handler` returns: tail string - `java.lang.String`
