Adds extra level recognizable by this formatter and Level.parse()- Parameters:
name
- name of the levelintValue
- integer value of the levelid
- one character id to use for this level. If it'snull
first character of the level name will be usedresourceBundleName
- resource bundle to use for level name translation- Returns:
- newly generated level instance
-
addCustomLevel
public static void addCustomLevel(java.util.logging.Level level, java.lang.String id)
Adds level to be treated specially by this formatter.- Parameters:
level
- level to be added to the special listid

sets new customer header format specification- Parameters:
header
- array of Strings containing optional parameters with name of the header value to use in them. For example:Java version: {java.version}
.
-
getTimeZoneID
public java.lang.String getTimeZoneID()
Returns the ID of the time zone to be used in the formatted log record header timestamp- Returns:
- time zone ID
- See Also:
TimeZone
-
setTimeZoneID
public void setTimeZoneID(java.lang.String timeZoneId)
Sets the ID of the time zone to be used in the formatted log record header timestamp- Parameters:

Returns the formatter's locale that will be used to localize the log record's date timestamp and message.- Returns:
- the locale that will be used to localize the log record
-
setDateFormat
public void setDateFormat(java.util.Locale locale, boolean isoDateFormat)
Sets the formatter locale and the dateFormat that will be used to localize a log record being formatted. The formatter locale will be used whenformatRecord(RepositoryLogRecord)
is invoked. It is possible to format a log record with a locale other than one set by this method usingformatRecord(RepositoryLogRecord, Locale)
. the formatter locale will be set to the system locale until this method gets invoked. The dateFormat can be either the default format or the ISO-8601 format.- Parameters:
locale
