Class NodeBreaker

java.lang.Object
  |
  +--org.mmbase.module.community.NodeBreaker

All Implemented Interfaces:

java.lang.Runnable

Deprecated. The NodeBreaker is a temporary solution (not the best code I ever wrote, either, but it should not be too slow and will have to do for now). It would be much better to incorporate 'expiration time' in the TemporaryNodeManager or a temporary node cloud. As such, avoid using this class in the future.

public class NodeBreaker

extends java.lang.Object

implements java.lang.Runnable

NodeBreaker stores temporary nodes with an expiration time. After this has expired the node is removed.
