Class SingleServerClusterManager

java.lang.Object
  lumis.portal.cluster.AbstractClusterManager
      lumis.portal.cluster.SingleServerClusterManager

All Implemented Interfaces:

IClusterManager

public class SingleServerClusterManager
extends AbstractClusterManager

The cluster manager implementation for single server (without cluster) deployment. In a single server environment the sending process triggers the receiving process immediately. As a consequence of this, the transmission consequences happens synchronously, but the same may not happen at a multi-server environment.

Since:

4.0.0
