| java.rmi.activation |
|
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.
@since 1.2

| Java Source File Name | Type | Comment |
| Activatable.java | Class | The Activatable class provides support for remote
objects that require persistent access over time and that
can be activated by the system. |
| ActivateFailedException.java | Class | This exception is thrown by the RMI runtime when activation
fails during a remote call to an activatable object. |
| ActivationDesc.java | Class | 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.java | Class | General exception used by the activation interfaces.
As of release 1.4, this exception has been retrofitted to conform to
the general purpose exception-chaining mechanism. |
| ActivationGroup.java | Class | 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.java | Class | 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 name,
- the group's code location (the location of the group's class), and
- a "marshalled" object that can contain group specific
initialization data.
|
| ActivationGroupID.java | Class | 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. |
| ActivationID.java | Class | Activation makes use of special identifiers to denote remote
objects that can be activated over time. |
| ActivationInstantiator.java | Interface | An ActivationInstantiator is responsible for creating
instances of "activatable" objects. |
| ActivationMonitor.java | Interface | 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.java | Interface | The ActivationSystem provides a means for registering
groups and "activatable" objects to be activated within those groups. |
| Activator.java | Interface | The Activator facilitates remote object activation. |
| UnknownGroupException.java | Class | An UnknownGroupException is thrown by methods of classes and
interfaces in the java.rmi.activation package when the
ActivationGroupID parameter to the method is determined to be
invalid, i.e., not known by the ActivationSystem. |
| UnknownObjectException.java | Class | An UnknownObjectException is thrown by methods of classes and
interfaces in the java.rmi.activation package when the
ActivationID parameter to the method is determined to be
invalid. |
