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");

Method Detail

getLogWriter

public static LogWriter getLogWriter(java.lang.String gr,
                                     byte prio)

Use this static method to get a new LogWriter for a specified group and priority.

Parameters:

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

prio - the priority of this LogWriter's messages

Returns:

new LogWriter instance

println

public void println(java.lang.String str)

Append the string to the Buffer and then flush the whole Buffer as a single string to the log.
