Class _ServantLocatorStub

Implemented Interfaces:
IDLEntity, Object, Serializable, ServantLocator, ServantLocatorOperations, ServantManager, ServantManagerOperations
public class _ServantLocatorStub
extends ObjectImpl
implements ServantLocator, Serializable
The ServantLocator stub is an optional base for the servant locators. This stub cannot accept remote invocations, as methods in ServantLocatorOperations take POA as one of parameters. Both JDK 1.5 API and OMG specifies that POA is a local object that must not be transferred to the remote invocation target.

You do not need to derive your servant locator from this stub, it is enough to implement the ServantLocator interface. But you may choose to do this if you need its functional _ids() method or want to keep default behavior during per- or post- invokcations.

_ids

public String[] _ids()
Return the array of repository ids for this object, stating that it is both Servant locator and Servant manager.
Overrides:
_ids in interface ObjectImpl
Returns:
{ "IDL:omg.org/PortableServer/ServantLocator:1.0", "IDL:omg.org/PortableServer/ServantManager:1.0" }, always.

postinvoke

public void postinvoke(byte[] Object_id,
                       POA poa,
                       String method,
                       Object cookie,
                       Servant servant)
It is your responsibility to take the postinvoke actions, if any, by overriding this method. The default method does nothing.
Specified by:
postinvoke in interface ServantLocatorOperations
See Also:
ServantLocatorOperations.postinvoke(byte[],POA,String,Object,Servant)

preinvoke

public Servant preinvoke(byte[] Object_id,
                         POA poa,
                         String method,
                         CookieHolder cookie)
            throws ForwardRequest
It is your responsibility to take the preinvoke actions, if any, and also supply an appropriate servant for the current invocation. The default method instructs POA that the servant cannot be provided by locator. The OBJ_ADAPTER exception will be thrown by POA, unless it uses the available default servant for all invocations.
Specified by:
preinvoke in interface ServantLocatorOperations
