Class ServantActivatorPOA

java.lang.Object
  org.omg.PortableServer.Servant
      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.

Constructor Detail

ServantActivatorPOA

public ServantActivatorPOA()

_invoke

public OutputStream _invoke(String $method,
                            InputStream in,
                            ResponseHandler $rh)

Description copied from interface: InvokeHandler

Invoked 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:

_invoke in interface InvokeHandler

Parameters:

$method - The method name.

in - The InputStream containing the marshalled arguments.

$rh - The ResponseHandler which the servant uses to construct a proper reply

Returns:

The OutputStream created by the ResponseHandler which contains the marshalled reply

_all_interfaces

public String[] _all_interfaces(POA poa,
