java.rmi.activation
Class ActivationGroupDesc

java.lang.Object
  java.rmi.activation.ActivationGroupDesc

All Implemented Interfaces:: java.io.Serializable

public final class ActivationGroupDesc
extends java.lang.Object
implements java.io.Serializable

Contains information, necessary to create of recreate the activation objects. The group descriptor contains:

The name of the group's class. This class is derived from the ActivationGroup.
The group class code location.
The marshalled object that contains the group specific initialization information

The groups are created by the ActivationGroup.createGroup(java.rmi.activation.ActivationGroupID, java.rmi.activation.ActivationGroupDesc, long) 55 method that expectes the group class to have the two parameter constructor, the first parameter being the ActivationGroupID and the second the java.rmi.MarshalledObject.

Nested Class Summary

static class ActivationGroupDesc.CommandEnvironment
          Contains the startup options for the ActivationGroup implementations.
