Method Details

etherealize

public void etherealize(byte[] Object_Id,
                        POA poa,
                        Servant servant,
                        boolean cleanup_in_progress,
                        boolean remaining_activations)
This method is invoked whenever a servant for an object is deactivated, assuming the POA has the USE_SERVANT_MANAGER and RETAIN policies.
Parameters:
Object_Id - the Id of the object being deactivated.
poa - the POA in those scope the object was active.
servant - the servant, serving the object being deactivated.
cleanup_in_progress - if true, this method was called from due deactivation or destruction operation. False indicates that the method was called due other reasons.
remaining_activations - if true, at the invocation moment the passed servant is also associated with other objects in the active object map of the given POA.

incarnate

public Servant incarnate(byte[] Object_Id,
                         POA poa)
            throws ForwardRequest
This method is invoked whenever the POA receives a request for an object that is not currently active, assuming the POA has the USE_SERVANT_MANAGER and RETAIN policies. The user-supplied servant manager is responsible for locating or creating an appropriate servant that corresponds to the ObjectId value. The subsequent requests with the same ObjectId value will be delivered directly to that servant without invoking the servant manager.
Parameters:
Object_Id - the ObjectId value associated with the incoming request.
poa - the POA in which the object is being activated.
Returns:
a servant that will be used to process the incoming request.
Throws:
ForwardRequest - if the activator decides to forward the request to another object. The exception contains the object that should handle this request. This object is usually remote, but can also be local. The throws exception will forward all subsequent requests till the new activation.
