Class ForumMMBaseSyncer

java.lang.Object

org.mmbase.applications.mmbob.ForumMMBaseSyncer

All Implemented Interfaces:

Runnable

public class ForumMMBaseSyncer
extends Object
implements Runnable

The syncer for Nodes used in MMBob. There can be different types of syncing mechanisms: slow for things like statistics and fast for really important things like postings, userinfo, etc This object is responsible for calling Node.commit(), of the MMBase nodes involved in MMBob. It does that only to spare the MMBase database. It maintains a queue of 'dirty nodes', and sometimes calls commit on one and cleans it up.
