Class LogManager

java.lang.Object
  java.util.logging.LogManager
      com.sun.jini.logging.LogManager

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 com.sun.jini.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 com.sun.jini.logging.LogManager to log information at the following logging levels:

com.sun.jini.logging.LogManager

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
