java.lang.Objectjava.rmi.activation.ActivationGroupDesc
An activation group descriptor contains the information necessary to create/recreate an activation group in which to activate objects. Such a descriptor contains:
The group's class must be a concrete subclass of
ActivationGroup. A subclass of
ActivationGroup is created/recreated via the
ActivationGroup.createGroup static method that invokes
a special constructor that takes two arguments:
ActivationGroupID, and
