public interface POAManagerOperations
POAManager
.
These operations can turn the associated POAs to and from holding,
active and discarding states, but the incative state is irreversible.
The inactivated POAs can only be recreated after they were destroyed.Modifier and Type | Method and Description |
---|---|
void |
activate()
Turns the associated POAs into active state, allowing them to receive
and process requests.
|
void |
deactivate(boolean etherealize_objects,
boolean wait_for_completion)
Turns the asociated POAs into inactive state.
|
void |
discard_requests(boolean wait_for_completion)
Turns the associated POAs into discaring state.
|
State |
get_state()
Get the state of the POA manager.
|
void |
hold_requests(boolean wait_for_completion)
Turns the associated POAs into holding state.

void activate() throws AdapterInactive
AdapterInactive
- if the POAs are in the inactive state. If
once inactivated, the POA cannot be activated again.
This method can only be called to leave the holding or discarding state.void deactivate(boolean etherealize_objects, boolean wait_for_completion) throws AdapterInactive
Turns the asociated POAs into inactive state. The POAs in the incative
state will reject new requests. A cliet, trying to invoke an
object, belonging to the inactivated POA, will receive the remote exception
(OBJ_ADAPTER
, minor code 0x535503ea, incomplete).
If the POA is once inactivated, it cannot be activated again. The operation is used when the associated POAs are to be shut down.
Some independent implementations may set the minor code of the OBJ_ADAPTER to 1, as recommended by OMG (formal/04-03-12). The interoperable systems should expect any of these two values.
etherealize_objects
- if true, the servant managers of the
associated POAs, having RETAIN and USE_SERVANT_MANAGER policies,
will receive a call of ServantActivatorOperations.etherealize(byte[], org.omg.PortableServer.POA, org.omg.PortableServer.Servant, boolean, boolean)
.wait_for_completion
- if true, the method call suspends the current
thread till POAs complete the requests they are currently processing. If
false, the method returns immediately.
AdapterInactive
- if the POAs are already in the inactive state.POAOperations.destroy(boolean, boolean)
void discard_requests(boolean wait_for_completion) throws AdapterInactive
Turns the associated POAs into discaring state. In this state, the POAs
discard the incoming requests. This mode is used in situations when
the server is flooded with requests. The client receives remote exception
(TRANSIENT
, minor code 0x535503e9, incomplete).
Some independent implementations may set the minor code of the TRANSIENT to 1, as recommended by OMG (formal/04-03-12). The interoperable systems should expect any of these two values.
wait_for_completion
- if true, the method call suspends the current
thread till POAs complete the requests they are currently processing. If
false, the method returns immediately.AdapterInactive
- if the POAs are in the inactive state.void hold_requests(boolean wait_for_completion) throws AdapterInactive
wait_for_completion
- if true, the method call suspends the current
thread till POAs complete the requests they are currently processing. If
false, the method returns immediately.AdapterInactive
- if the POAs are in the inactive state.
