- org.omg.PortableServer.ServantActivatorPOA
-
- All Implemented Interfaces:
- InvokeHandler, ServantActivatorOperations, ServantManagerOperations
public abstract class ServantActivatorPOA extends Servant implements ServantActivatorOperations, InvokeHandler
When the POA has the RETAIN policy it uses servant managers that are ServantActivators.

Method Detail
_invoke
public OutputStream _invoke(String $method, InputStream in, ResponseHandler $rh)
Description copied from interface:InvokeHandlerInvoked by the ORB to dispatch a request to the servant. ORB passes the method name, an InputStream containing the marshalled arguments, and a ResponseHandler which the servant uses to construct a proper reply. Only CORBA SystemException may be thrown by this method. The method must return an OutputStream created by the ResponseHandler which contains the marshalled reply. A servant must not retain a reference to the ResponseHandler beyond the lifetime of a method invocation. Servant behaviour is defined as follows:1. Determine correct method, and unmarshal parameters from InputStream.
2. Invoke method implementation.
3. If no user exception, create a normal reply using ResponseHandler.
4. If user exception occurred, create exception reply using ResponseHandler.
5. Marshal reply into OutputStream returned by ResponseHandler.
6. Return OutputStream to ORB.
- Specified by:

-
$method- The method name. -
in- TheInputStreamcontaining the marshalled arguments. -
$rh- TheResponseHandlerwhich the servant uses to construct a proper reply - Returns:
