Method Detail

initialize

public void initialize(GridServiceBase base)
                throws GridServiceException

Description copied from interface: FactoryCallback

associates this object with its GridServiceBase service. This method is called when the first instance creation is requested.

Specified by:

initialize in interface FactoryCallback

Parameters:

base - factory service that this factory callback should create services for

Throws:

GridServiceException - if the callback object could not be initialized

createServiceObject

public GridServiceBase createServiceObject(ExtensibilityType creation)
                                    throws GridServiceException

Description copied from interface: FactoryCallback

creates a new Grid service instance that implements the GridServiceBase interface

Specified by:

createServiceObject in interface FactoryCallback

Parameters:

creation - parameters the client may pass to the factory at creation time

Throws:

GridServiceException - if the service instance could not be created

preDestroy

public void preDestroy(GridContext context)
                throws GridServiceException

Description copied from interface: GridServiceCallback

called just before a service gets destroyed. After this call is made the framework removes all knowledge about the service, so it is a good place to clean up service resources. Note that this call can be triggered both by a client initiated destroy call, as well as a framework initiated softstate timeout.

Specified by:

preDestroy in interface GridServiceCallback

Parameters:

context - state information currently associated with the service

Throws:

GridServiceException - if the destruction failed (will be reported to clients in the case of explicit destroy calls)

postCreate

public void postCreate(GridContext context)
                throws GridServiceException

Description copied from interface: GridServiceCallback

called when a service has been created and all of its configuration has been set up.

Specified by:

postCreate in interface GridServiceCallback

Parameters:

context - state information currently associated with the service that was created.

Throws:

GridServiceException - if the service creation should be aborted

activate

public void activate(GridContext context)
              throws GridServiceException

Description copied from interface: GridServiceCallback

called when a service becomes active after having been deactivated. A service is always activated before any methods can be called on it.

Specified by:

activate in interface GridServiceCallback

Parameters:

context - state information currently asociated with the service

Throws:

GridServiceException - if the service activation should be aborted

deactivate

public void deactivate(GridContext context)
                throws GridServiceException

Description copied from interface: GridServiceCallback

called just before a service gets deactivated. When a service is deactivated it is subject to garbage collection, so if state is to be survive deactivation it has to be checkpointed into persistent storage. A deactivated service is however still discoverable by clients.

Specified by:

deactivate in interface GridServiceCallback

Parameters:

context - state information currently associated with the service

Throws:

GridServiceException - if the service deactivation failed

preCreate

public void preCreate(GridServiceBase base)
               throws GridServiceException

Description copied from interface: GridServiceCallback

called when a service object is created.

Specified by:

preCreate in interface GridServiceCallback

Parameters:

base - the Grid service that is in the process of creating this service object, or if this is a persistent Grid service it points to the service to be created.

Throws:

GridServiceException - if the service should not be created
