## Interface ActivationInstantiator

- All Superinterfaces:
    Remote
  All Known Implementing Classes:
    ActivationGroup, ActivationGroup_Stub

      public interface ActivationInstantiator
      extends Remote

  An `ActivationInstantiator` is responsible for creating instances of "activatable" objects. A concrete subclass of `ActivationGroup` implements the `newInstance` method to handle creating objects within the group.
  Since:
    1.2
  See Also:
    `ActivationGroup`

- - ### Method Summary

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description

    `MarshalledObject<? extends Remote>` | `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`.

- - ### Method Detail

    - #### newInstance

          MarshalledObject<? extends Remote> newInstance(ActivationID id,
                                                         ActivationDesc desc)
                                                  throws ActivationException,
                                                         RemoteException

      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`. The instantiator is responsible for:
      - determining the class for the object using the descriptor's `getClassName` method,
      - loading the class from the code location obtained from the descriptor (using the `getLocation` method),
      - creating an instance of the class by invoking the special "activation" constructor of the object's class that takes two arguments: the object's `ActivationID`, and the `MarshalledObject` containing object specific initialization data, and
      - returning a MarshalledObject containing the stub for the remote object it created
      Parameters:
        `id` - the object's activation identifier
        `desc` - the object's descriptor
      Returns:
        a marshalled object containing the serialized representation of remote object's stub
      Throws:
        `ActivationException` - if object activation fails
        `RemoteException` - if remote call fails
      Since:
        1.2
