virtual

Member Function Documentation

◆ activate()

virtual void Ice::ObjectAdapter::activate ( )

pure virtual

Activate all endpoints that belong to this object adapter.

After activation, the object adapter can dispatch requests received through its endpoints.

See also: hold; deactivate

◆ add()

virtual ObjectPrx Ice::ObjectAdapter::add	(	const ObjectPtr &	servant,
		const Identity &	id )

pure virtual

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.

Parameters

servant	The servant to add.
id	The identity of the Ice object that is implemented by the servant.

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

See also: Identity; addFacet; addWithUUID; remove; find

◆ addDefaultServant()

virtual void Ice::ObjectAdapter::addDefaultServant	(	const ObjectPtr &	servant,
		const ::std::string &	category )

pure virtual

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:

The object adapter tries to find a servant for the identity and facet in the Active Servant Map.
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.
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.
If no servant has been found by any of the preceding steps, the object adapter gives up and the caller receives ObjectNotExistException or FacetNotExistException.

Parameters

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

See also: removeDefaultServant; findDefaultServant

◆ addFacet()

virtual ObjectPrx Ice::ObjectAdapter::addFacet	(	const ObjectPtr &	servant,
		const Identity &	id,
		const ::std::string &	facet )

pure virtual

Like add, but with a facet.

Calling add(servant, id) is equivalent to calling addFacet with an empty facet.

Parameters

servant	The servant to add.
id	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.

See also: Identity; add; addFacetWithUUID; removeFacet; findFacet

◆ addFacetWithUUID()

virtual ObjectPrx Ice::ObjectAdapter::addFacetWithUUID	(	const ObjectPtr &	servant,
		const ::std::string &	facet )

pure virtual

Like addWithUUID, but with a facet.

Calling addWithUUID(servant) is equivalent to calling addFacetWithUUID with an empty facet.

Parameters

servant	The servant to add.
facet	The facet. An empty facet means the default facet.

Returns: A proxy that matches the generated UUID identity, facet, and this object adapter.

See also: Identity; addFacet; addWithUUID; removeFacet; findFacet

◆ addServantLocator()

virtual void Ice::ObjectAdapter::addServantLocator	(	const ServantLocatorPtr &	locator,
		const ::std::string &	category )

pure virtual

Add a Servant Locator to this object adapter.

Adding a servant locator for a category for which a servant locator 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:

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

Only one locator for the empty category can be installed.

Parameters

locator	The locator to add.
category	The category for which the Servant Locator can locate servants, or an empty string if the Servant Locator does not belong to any specific category.

See also: Identity; removeServantLocator; findServantLocator; ServantLocator

◆ addWithUUID()

virtual ObjectPrx Ice::ObjectAdapter::addWithUUID ( const ObjectPtr & servant )

pure virtual

Add a servant to this object adapter's Active Servant Map, using an automatically generated UUID as its identity.

Note that the generated UUID identity can be accessed using the proxy's ice_getIdentity operation.

Parameters

servant The servant to add.

Returns: A proxy that matches the generated UUID identity and this object adapter.

See also: Identity; add; addFacetWithUUID; remove; find

◆ createDirectProxy()

virtual ObjectPrx Ice::ObjectAdapter::createDirectProxy ( const Identity & id ) const

pure virtual

Create a direct proxy for the object with the given identity.

The returned proxy contains this object adapter's published endpoints.

Parameters

id	The object's identity.

Returns: A proxy for the object with the given identity.

See also: Identity

◆ createIndirectProxy()

virtual ObjectPrx Ice::ObjectAdapter::createIndirectProxy ( const Identity & id ) const

pure virtual

Create an indirect proxy for the object with the given identity.

If this object adapter is configured with an adapter id, the return value refers to the adapter id. Otherwise, the return value contains only the object identity.

Parameters

id	The object's identity.

Returns: A proxy for the object with the given identity.

See also: Identity

◆ createProxy()

virtual ObjectPrx Ice::ObjectAdapter::createProxy ( const Identity & id ) const

pure virtual

Create a proxy for the object with the given identity.

If this object adapter is configured with an adapter id, the return value is an indirect proxy that refers to the adapter id. If a replica group id is also defined, the return value is an indirect proxy that refers to the replica group id. Otherwise, if no adapter id is defined, the return value is a direct proxy containing this object adapter's published endpoints.

Parameters

id	The object's identity.

Returns: A proxy for the object with the given identity.

See also: Identity

◆ deactivate()

virtual void Ice::ObjectAdapter::deactivate	(		)
throw	(	)

pure virtual

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

See also: activate; hold; waitForDeactivate; Communicator::shutdown

◆ destroy()

virtual void Ice::ObjectAdapter::destroy	(		)
throw	(	)

pure virtual

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.

See also: deactivate; waitForDeactivate; Communicator::destroy

◆ find()

virtual ObjectPtr Ice::ObjectAdapter::find ( const Identity & id ) const

pure virtual

Look up a servant in this object adapter's Active Servant Map by the identity of the Ice object it implements.

This operation only tries to look up a servant in the Active Servant Map. It does not attempt to find a servant by using any installed ServantLocator.

Parameters

id	The identity of the Ice object for which the servant should be returned.

Returns: The servant that implements the Ice object with the given identity, or null if no such servant has been found.

See also: Identity; findFacet; findByProxy
