Method Detail

newServiceStarter

public ManagedServiceConfiguration.ManagedServiceStarter newServiceStarter(IServiceListener listener)
                                                                    throws Exception

Not supported - use #newServiceStarter(JiniFederation, IServiceListener, String) instead.

Overrides:

newServiceStarter in class JavaServiceConfiguration

Throws:

UnsupportedOperationException - always.

Exception - if there is a problem creating the service starter.

newServiceStarter

public ManagedServiceConfiguration.ManagedServiceStarter newServiceStarter(JiniFederation fed,
                                                                           IServiceListener listener,

Factory method returns an object that may be used to (re-)start a service.

Parameters:

fed -

listener -

logicalServiceZPath - The path to the logical service whose instance will be started.

attributes - This provides the information required to restart a persistent service. When not given a new service instance will be started. When given, the same services instance will be restarted.

Throws:

Exception - if there is a problem creating the service starter.

newLogicalServiceTask

public ManageLogicalServiceTask<ManagedServiceConfiguration> newLogicalServiceTask(JiniFederation fed,
                                                                                   IServiceListener listener,

Return a task that will correct any imbalance between the ServiceConfiguration and the #of logical services.

Parameters:

fed -

listener -

configZPath - The zpath of the ManagedServiceConfiguration

children - The list of logical service instances. These are the children of the ManagedServiceConfiguration znode.

Returns:
