public final class DistributedEquiv
extends java.lang.Object

Returns:

Distributed Equivalent System

Throws:

ServerConfigException - if exception is encountered

stop

public void stop()
          throws ServerConfigException

Terminate the Distributed Equivalent System

Throws:

ServerConfigException - if error during stopping
