  _ServantActivatorStub, ServantActivatorPOA

public interface ServantActivatorOperations
extends ServantManagerOperations

When the POA has the RETAIN policy it uses servant managers that are ServantActivators.

Method Summary
`void` | `etherealize(byte[] oid, POA adapter, Servant serv, boolean cleanup_in_progress, boolean remaining_activations)` This operation is invoked whenever a servant for an object is deactivated, assuming the POA has the USE_SERVANT_MANAGER and RETAIN policies.
`Servant` | `incarnate(byte[] oid, POA adapter)` This operation is invoked by the POA 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.

Method Detail

### incarnate

    public Servant incarnate(byte[] oid,
                             POA adapter)
                      throws ForwardRequest

  This operation is invoked by the POA 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.

  Parameters:
    `oid` - object Id associated with the object on the request was made.
    `adapter` - object reference for the POA in which the object is being activated.
  Returns:
    Servant corresponding to oid is created or located by the user supplied servant manager.
  Throws:
    `ForwardRequest` - to indicate to the ORB that it is responsible for delivering the current request and subsequent requests to the object denoted in the forward_reference member of the exception.

### etherealize

    public void etherealize(byte[] oid,
                            POA adapter,
                            Servant serv,
                            boolean cleanup_in_progress,
                            boolean remaining_activations)

  This operation is invoked whenever a servant for an object is deactivated, assuming the POA has the USE_SERVANT_MANAGER and RETAIN policies.

  Parameters:
    `oid` - object Id associated with the object being deactivated.
    `adapter` - object reference for the POA in which the object was active.
    `serv` - contains reference to the servant associated with the object being deactivated.
    `cleanup_in_progress` - if TRUE indicates that destroy or deactivate is called with etherealize_objects param of TRUE. FALSE indicates that etherealize was called due to other reasons.
    `remaining_activations` - indicates whether the Servant Manager can destroy a servant. If set to TRUE, the Servant Manager should wait until all invocations in progress have completed.
