Class LogWriter

java.lang.Object
  net.juniper.smgt.lib.logging.LogEventBase
      net.juniper.smgt.lib.logging.LogWriter

All Implemented Interfaces:

net.juniper.smgt.lib.logging.LogEventSource, net.juniper.smgt.lib.logging.LogWriterI

public class LogWriter
extends net.juniper.smgt.lib.logging.LogEventBase
implements net.juniper.smgt.lib.logging.LogWriterI

This class prints messages to a log. Simply create a LogWriter with one of the static getLogWriter() methods and then use println(message) to log message. Many modules initialize multiple LogWriters for different loglevels. Optionally use the isActive() method to check if the LogWriter has listeners attached before composing long messages. Example:

 LogWriter err   = LogWriter.getLogWriter("test", Logger.ERROR);
 LogWriter log   = LogWriter.getLogWriter("test", Logger.INFO);
 LogWriter debug = LogWriter.getLogWriter("test", Logger.DEBUG);
 
 log.println("Will test logging");
 if (debug.isActive())
     debug.println("This String" + "is only generated" +
                   "if there is someone to listen");

Parameters:

gr - the group that this LogWriter's messages will belong to

prio - the priority of this LogWriter's messages

Returns:

new LogWriter instance
