- - ### Uses of ActivationID in java.rmi.activation

    Methods in java.rmi.activation that return ActivationID
    Modifier and Type | Method and Description
    --- | ---
    `static ActivationID` | Activatable.`exportObject(Remote obj, String location, MarshalledObject<?> data, boolean restart, int port)` Registers an activation descriptor (with the specified location, data, and restart mode) for the specified object, and exports that object with the specified port.
    `static ActivationID` | Activatable.`exportObject(Remote obj, String location, MarshalledObject<?> data, boolean restart, int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf)` Registers an activation descriptor (with the specified location, data, and restart mode) for the specified object, and exports that object with the specified port, and the specified client and server socket factories.
    `protected ActivationID` | Activatable.`getID()` Returns the object's activation identifier.
    `ActivationID` | ActivationSystem.`registerObject(ActivationDesc desc)` The `registerObject` method is used to register an activation descriptor, `desc`, and obtain an activation identifier for a activatable remote object.

    Methods in java.rmi.activation with parameters of type ActivationID
    Modifier and Type | Method and Description
    --- | ---
    `MarshalledObject<? extends Remote>` | Activator.`activate(ActivationID id, boolean force)` Activate the object associated with the activation identifier, `id`.
    `protected void` | ActivationGroup.`activeObject(ActivationID id, MarshalledObject<? extends Remote> mobj)` This protected method is necessary for subclasses to make the `activeObject` callback to the group's monitor.
    `void` | ActivationMonitor.`activeObject(ActivationID id, MarshalledObject<? extends Remote> obj)` Informs that an object is now active.
    `abstract void` | ActivationGroup.`activeObject(ActivationID id, Remote obj)` The group's `activeObject` method is called when an object is exported (either by `Activatable` object construction or an explicit call to `Activatable.exportObject`.
    `static Remote` | Activatable.`exportObject(Remote obj, ActivationID id, int port)` Export the activatable remote object to the RMI runtime to make the object available to receive incoming calls.
    `static Remote` | Activatable.`exportObject(Remote obj, ActivationID id, int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf)` Export the activatable remote object to the RMI runtime to make the object available to receive incoming calls.
    `ActivationDesc` | ActivationSystem.`getActivationDesc(ActivationID id)` Returns the activation descriptor, for the object with the activation identifier, `id`.
    `static boolean` | Activatable.`inactive(ActivationID id)` Informs the system that the object with the corresponding activation `id` is currently inactive.
    `boolean` | ActivationGroup.`inactiveObject(ActivationID id)` The group's `inactiveObject` method is called indirectly via a call to the `Activatable.inactive` method.
    `void` | ActivationMonitor.`inactiveObject(ActivationID id)` An activation group calls its monitor's `inactiveObject` method when an object in its group becomes inactive (deactivates).
    `MarshalledObject` | ActivationGroup_Stub.`newInstance(ActivationID id, ActivationDesc desc)` Stub method for `ActivationGroup.newInstance`.
    `MarshalledObject<? extends Remote>` | ActivationInstantiator.`newInstance(ActivationID id, ActivationDesc desc)` The activator calls an instantiator's `newInstance` method in order to recreate in that group an object with the activation identifier, `id`, and descriptor, `desc`.
    `ActivationDesc` | ActivationSystem.`setActivationDesc(ActivationID id, ActivationDesc desc)` Set the activation descriptor, `desc` for the object with the activation identifier, `id`.
    `static void` | Activatable.`unregister(ActivationID id)` Revokes previous registration for the activation descriptor associated with `id`.
    `void` | ActivationSystem.`unregisterObject(ActivationID id)` Remove the activation id and associated descriptor previously registered with the `ActivationSystem`; the object can no longer be activated via the object's activation id.

    Constructors in java.rmi.activation with parameters of type ActivationID
    Constructor and Description
    `Activatable(ActivationID id, int port)` Constructor used to activate/export the object on a specified port.
    `Activatable(ActivationID id, int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf)` Constructor used to activate/export the object on a specified port.
