Class ActivationGroupID

java.lang.Object
  java.rmi.activation.ActivationGroupID

All Implemented Interfaces:

Serializable

public class ActivationGroupID
extends Object
implements Serializable

The identifier for a registered activation group serves several purposes:

• identifies the group uniquely within the activation system, and
• contains a reference to the group's activation system so that the group can contact its activation system when necessary.

The ActivationGroupID is returned from the call to ActivationSystem.registerGroup and is used to identify the group within the activation system. This group id is passed as one of the arguments to the activation group's special constructor when an activation group is created/recreated.
