Interface Summary Interface Description 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. -
Class Summary Class Description Activatable TheActivatable
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 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.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.ActivationGroup_Stub ActivationGroup_Stub
is a stub class for the subclasses ofjava.rmi.activation.ActivationGroup
that are exported as ajava.rmi.server.UnicastRemoteObject
.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 Exception Description 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 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.
Package java.rmi.activation Description
Implementations are not required to support the activation mechanism. If activation is not supported by this implementation, several specific activation API methods are all required to throw UnsupportedOperationException
. If activation is supported by this implementation, these methods must never throw UnsupportedOperationException
. These methods are denoted by the presence of an entry for UnsupportedOperationException
in the Throws section of each method's specification.
