Classes in java.rmi.activation used by java.rmi.activation Class Description ActivationDesc An activation descriptor contains the information necessary to activate an object: the object's group identifier, the object's fully-qualified class name, the object's code location (the location of the class), a codebase URL path, the object's restart "mode", and, a "marshalled" object that can contain object specific initialization data.ActivationException General exception used by the activation interfaces.ActivationGroup AnActivationGroup
is responsible for creating new instances of "activatable" objects in its group, informing itsActivationMonitor
when either: its object's become active or inactive, or the group as a whole becomes inactive.ActivationGroupDesc An activation group descriptor contains the information necessary to create/recreate an activation group in which to activate objects.ActivationGroupDesc.CommandEnvironment Startup options for ActivationGroup implementations.ActivationGroupID 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.ActivationID Activation makes use of special identifiers to denote remote objects that can be activated over time.ActivationInstantiator AnActivationInstantiator
is responsible for creating instances of "activatable" objects.ActivationMonitor AnActivationMonitor
is specific to anActivationGroup
and is obtained when a group is reported active via a call toActivationSystem.activeGroup
(this is done internally).ActivationSystem TheActivationSystem
provides a means for registering groups and "activatable" objects to be activated within those groups.Activator TheActivator
facilitates remote object activation.UnknownGroupException AnUnknownGroupException
is thrown by methods of classes and interfaces in thejava.rmi.activation
package when theActivationGroupID
parameter to the method is determined to be invalid, i.e., not known by theActivationSystem
.UnknownObjectException AnUnknownObjectException
is thrown by methods of classes and interfaces in thejava.rmi.activation
package when theActivationID
parameter to the method is determined to be invalid.
