java.rmi.activation
public interface: ActivationInstantiator [javadoc | source]

All Implemented Interfaces:
Remote

All Known Implementing Classes:
ActivationGroup_Stub, ActivationGroup

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.

Method from java.rmi.activation.ActivationInstantiator Summary:
newInstance

Method from java.rmi.activation.ActivationInstantiator Detail:
public MarshalledObject<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

 public MarshalledObject<Remote> newInstance(ActivationID id,
    ActivationDesc desc) throws ActivationException, RemoteExceptionThe 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
