Interface Summary | |
ActivationInstantiator | An ActivationInstantiator is responsible for creating
instances of "activatable" objects. |
ActivationMonitor | An ActivationMonitor is specific to an
ActivationGroup and is obtained when a group is
reported active via a call to
ActivationSystem.activeGroup (this is done
internally). |
ActivationSystem | The ActivationSystem provides a means for registering
groups and "activatable" objects to be activated within those groups.
|
Activator | The Activator facilitates remote object activation. |
Class Summary | |
Activatable | The Activatable class provides support for remote
objects that require persistent access over time and that
can be activated by the system. |
ActivationDesc | An activation descriptor contains the information necessary to activate an object: the object's group identifier, the object's class name, the object's code location (the location of the class), and a "marshalled" object that can contain object specific initialization data. |
ActivationGroup | An ActivationGroup is responsible for creating new
instances of "activatable" objects in its group, informing its
ActivationMonitor 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. |
Exception Summary | |
ActivateFailedException | This exception is thrown by the RMI runtime when activation fails during a remote call to an activatable object. |
ActivationException | General exception used by the activation interfaces. |
UnknownGroupException | |
UnknownObjectException |
Provides support for RMI Object Activation. A remote object's reference can be made ``persistent'' and later activated into a ``live'' object using the RMI activation mechanism.
