Class ServantLocatorPOA
- InvokeHandler, ServantLocatorOperations, ServantManagerOperations
The ServantLocator stub is an optional base for the
servant locators. It cannot serve 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.
String[] | _all_interfaces(POA poa, byte[] Object_Id) - Returns an array of interfaces, supported by the servant locator.
|
OutputStream | _invoke(String method, InputStream input, ResponseHandler handler) - Our implementation will not call this method.
|
ServantLocator | _this() - Return the complete instance of the servant activator, based on
the current class (ServantActivatorPOA or derived).
|
ServantLocator | _this(ORB orb) - Return the complete instance of the servant activator, based on
the current class (ServantActivatorPOA or derived).
|
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.
|
Servant | preinvoke(byte[] Object_Id, POA poa, String method, CookieHolder cookie_holder) - It is your responsibility to take the preinvoke actions, if any,
and also supply an appropriate servant for the current invocation.

_this
public ServantLocator _this()
Return the complete instance of the servant activator, based on
the current class (ServantActivatorPOA or derived).
_this
public ServantLocator _this(ORB orb)
Return the complete instance of the servant activator, based on
the current class (ServantActivatorPOA or derived).
preinvoke
public Servant preinvoke(byte[] Object_Id,
POA poa,
String method,
CookieHolder cookie_holder)
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.
