Class NoDGC

java.lang.Object
  uka.karmi.rmi.DGC
      uka.karmi.nodgc.NoDGC

public final class NoDGC

extends DGC

The NoDGC is a dummy garbage collector that does nothing. It can not be used with JDK 1.2 and higher, because remote objects would die even if they are still referenced. As real garbage collection does not work with JDK 1.1 it can be uses there to save some processing time.
