Class ConsoleLog

java.lang.Object
  net.sf.taverna.raven.log.ConsoleLog

All Implemented Interfaces:

LogInterface

public class ConsoleLog
extends java.lang.Object
implements LogInterface

Implementation of LogInterface for simple System.err based printouts. To use this implementation, do:

 Log.setImplementation(new ConsoleLog());
 

This is a very simple implementation, that by default only logs messages at WARN or higher. This threshold can be changed by setting the level member. The destination output can be changed by setting the console member. Stack traces will be printed by default if provided, but this can be disabled by setting printStackTrace to false
