public class LogManager extends LogManager
Defines a LogManager that insures that the Levels.FAILED and Levels.HANDLED
fields, instances of Level, have been initialized, and that can
periodically check for changes to the logging configuration file and force
it to be reread. Use this class as the value of the
java.util.logging.manager system property to permit specifying
the symbolic names for the FAILED and HANDLED
logging levels in standard logging configuration files, or to allow changes
to the logging configuration file to be noticed.
The org.apache.river.logging.interval logging property (obtained
using LogManager.getProperty) specifies the time interval in milliseconds
between probes to see if the logging configuration file has changed;
periodic checking only takes place if the value is greater than zero. (If a
new logging configuration file is read, this property can be redefined.)
The logging configuration file is specified by the
java.util.logging.config.file system property (which is
sampled at every probe), if defined, otherwise it is the
logging.properties file in the lib subdirectory
of the directory specified by the java.home system property.
The file is read if the name of the file differs from that used in the
previous probe or if the file has a different modification time.
This implementation uses the Logger named
org.apache.river.logging.LogManager to log information at the
following logging levels:
| Level | Description |
|---|---|
WARNING | if an exception occurs while rereading the logging configuration file |
CONFIG | each time the logging configuration file is successfully reread |
CONFIG | termination of probes because interval is less than or equal to zero |
