ObjectAdapterI

public ObjectAdapterI(Instance instance,
                      Communicator communicator,
                      ObjectAdapterFactory objectAdapterFactory,
                      java.lang.String name,
                      RouterPrx router,
                      boolean noConfig)

Method Detail

getName

public java.lang.String getName()

Description copied from interface: ObjectAdapter

Get the name of this object adapter.

Specified by:

getName in interface ObjectAdapter

Returns:

This object adapter's name.

getCommunicator

public Communicator getCommunicator()

Description copied from interface: ObjectAdapter

Get the communicator this object adapter belongs to.

Specified by:

getCommunicator in interface ObjectAdapter

Returns:

This object adapter's communicator.

See Also:

Communicator

activate

public void activate()

Description copied from interface: ObjectAdapter

Activate all endpoints that belong to this object adapter. After activation, the object adapter can dispatch requests received through its endpoints.

Specified by:

activate in interface ObjectAdapter

See Also:

ObjectAdapter.hold(), ObjectAdapter.deactivate()

hold

public void hold()

Description copied from interface: ObjectAdapter

Temporarily hold receiving and dispatching requests. The object adapter can be reactivated with the ObjectAdapter.activate() operation.

Holding is not immediate, i.e., after ObjectAdapter.hold() returns, the object adapter might still be active for some time. You can use ObjectAdapter.waitForHold() to wait until holding is complete.

Specified by:

hold in interface ObjectAdapter

See Also:

ObjectAdapter.activate(), ObjectAdapter.deactivate(), ObjectAdapter.waitForHold()

waitForHold

public void waitForHold()

Description copied from interface: ObjectAdapter

Wait until the object adapter holds requests. Calling ObjectAdapter.hold() initiates holding of requests, and ObjectAdapter.waitForHold() only returns when holding of requests has been completed.

Specified by:

waitForHold in interface ObjectAdapter

See Also:

ObjectAdapter.hold(), ObjectAdapter.waitForDeactivate(), Communicator.waitForShutdown()

deactivate

public void deactivate()

Description copied from interface: ObjectAdapter

Deactivate all endpoints that belong to this object adapter. After deactivation, the object adapter stops receiving requests through its endpoints. Object adapters that have been deactivated must not be reactivated again, and cannot be used otherwise. Attempts to use a deactivated object adapter raise ObjectAdapterDeactivatedException; however, attempts to ObjectAdapter.deactivate() an already deactivated object adapter are ignored and do nothing. Once deactivated, it is possible to destroy the adapter to clean up resources and then create and activate a new adapter with the same name.

After ObjectAdapter.deactivate() returns, no new requests are processed by the object adapter. However, requests that have been started before ObjectAdapter.deactivate() was called might still be active. You can use ObjectAdapter.waitForDeactivate() to wait for the completion of all requests for this object adapter.

Specified by:

deactivate in interface ObjectAdapter

See Also:

ObjectAdapter.activate(), ObjectAdapter.hold(), ObjectAdapter.waitForDeactivate(), Communicator.shutdown()

waitForDeactivate

public void waitForDeactivate()

Description copied from interface: ObjectAdapter

Wait until the object adapter has deactivated. Calling ObjectAdapter.deactivate() initiates object adapter deactivation, and ObjectAdapter.waitForDeactivate() only returns when deactivation has been completed.

Specified by:

waitForDeactivate in interface ObjectAdapter

See Also:

ObjectAdapter.deactivate(), ObjectAdapter.waitForHold(), Communicator.waitForShutdown()

isDeactivated

public boolean isDeactivated()

Description copied from interface: ObjectAdapter

Check whether object adapter has been deactivated.

Specified by:

isDeactivated in interface ObjectAdapter

Returns:

Whether adapter has been deactivated.

See Also:

Communicator.shutdown()

destroy

public void destroy()

Description copied from interface: ObjectAdapter

Destroys the object adapter and cleans up all resources held by the object adapter. If the object adapter has not yet been deactivated, destroy implicitly initiates the deactivation and waits for it to finish. Subsequent calls to destroy are ignored. Once destroy has returned, it is possible to create another object adapter with the same name.

Specified by:

destroy in interface ObjectAdapter

See Also:

ObjectAdapter.deactivate(), ObjectAdapter.waitForDeactivate(), Communicator.destroy()

add

public ObjectPrx add(Object object,
                     Identity ident)

Description copied from interface: ObjectAdapter

Add a servant to this object adapter's Active Servant Map. Note that one servant can implement several Ice objects by registering the servant with multiple identities. Adding a servant with an identity that is in the map already throws AlreadyRegisteredException.

Specified by:

add in interface ObjectAdapter

Parameters:

object - The servant to add.

ident - The identity of the Ice object that is implemented by the servant.

Returns:

A proxy that matches the given identity and this object adapter.

                          Identity ident,
                          java.lang.String facet)

Description copied from interface: ObjectAdapter

Like ObjectAdapter.add(Ice.Object, Ice.Identity), but with a facet. Calling add(servant, id) is equivalent to calling ObjectAdapter.addFacet(Ice.Object, Ice.Identity, java.lang.String) with an empty facet.

Specified by:

addFacet in interface ObjectAdapter

Parameters:

object - The servant to add.

ident - The identity of the Ice object that is implemented by the servant.

facet - The facet. An empty facet means the default facet.

Returns:

A proxy that matches the given identity, facet, and this object adapter.

addDefaultServant

public void addDefaultServant(Object servant,
                              java.lang.String category)

Description copied from interface: ObjectAdapter

Add a default servant to handle requests for a specific category. Adding a default servant for a category for which a default servant is already registered throws AlreadyRegisteredException. To dispatch operation calls on servants, the object adapter tries to find a servant for a given Ice object identity and facet in the following order:

1. The object adapter tries to find a servant for the identity and facet in the Active Servant Map.
2. If no servant has been found in the Active Servant Map, the object adapter tries to find a default servant for the category component of the identity.
3. If no servant has been found by any of the preceding steps, the object adapter tries to find a default servant for an empty category, regardless of the category contained in the identity.
4. If no servant has been found by any of the preceding steps, the object adapter gives up and the caller receives ObjectNotExistException or FacetNotExistException.

Specified by:

addDefaultServant in interface ObjectAdapter

Parameters:

servant - The default servant.

category - The category for which the default servant is registered. An empty category means it will handle all categories.
