org.oddjob.logging.cache.LocalConsoleArchiver

All Implemented Interfaces:

ConsoleArchiver

public class LocalConsoleArchiver
extends java.lang.Object
implements ConsoleArchiver

An implementation of a ConsoleArchiver for the local JVM. An Explorer or Server job will attach this archiver to a job node to capture console output from that node and it's children down to a node which is a different console archiver ( because it's a separate process or is getting console output from a remote node).
