Constructor Details

ServiceAdminImpl

public ServiceAdminImpl(AbstractService service,
 Exporter exporter)
                 throws RemoteException

Constructs a ServiceAdminImpl.

Throws:

RemoteException

Method Details

getProxy

public ServiceAdmin getProxy()

Get the object to communicate with the ServiceAdminImpl

unexport

public void unexport(boolean force)

Unexport the ServiceAdmin

validateJoinManager

protected void validateJoinManager(JoinManager mgr)
                            throws RemoteException

Throw the RemoteException in case of JoinManager is null.

Throws:

RemoteException

destroy

public void destroy()
             throws RemoteException

Description copied from interface: DestroyAdmin

Destroy the service, if possible, including its persistent storage. This method should (in effect) spawn a separate thread to do the actual work asynchronously, and make a reasonable attempt to let this remote call return successfully. As such, a successful return from this method does not mean that the service has been destroyed. Although the service should make a reasonable attempt to let this remote call return successfully, the service must not wait indefinitely for other (in-progress and subsequent) remote calls to finish before proceeding to destroy itself. Once this method has been called, the service can, but need not, reject all other (in-progress and subsequent) remote calls to the service.

Specified by:

destroy in interface DestroyAdmin

Specified by:

destroy in interface ServiceAdmin

Throws:

RemoteException

getLookupAttributes

public Entry[] getLookupAttributes()
                            throws RemoteException

Description copied from interface: JoinAdmin

Get the current attribute sets for the service.

Specified by:

getLookupAttributes in interface JoinAdmin

Returns:

the current attribute sets for the service

Throws:

RemoteException

addLookupAttributes

public void addLookupAttributes(Entry[] attrSets)
                         throws RemoteException

Description copied from interface: JoinAdmin

Add attribute sets for the service. The resulting set will be used for all future joins. The attribute sets are also added to all currently-joined lookup services.

Specified by:

addLookupAttributes in interface JoinAdmin

Parameters:

attrSets - the attribute sets to add

Throws:

RemoteException

modifyLookupAttributes

public void modifyLookupAttributes(Entry[] attrSetTemplates,
 Entry[] attrSets)
                            throws RemoteException

Description copied from interface: JoinAdmin

Modify the current attribute sets, using the same semantics as ServiceRegistration.modifyAttributes. The resulting set will be used for all future joins. The same modifications are also made to all currently-joined lookup services.

Specified by:

modifyLookupAttributes in interface JoinAdmin

Parameters:

attrSetTemplates - the templates for matching attribute sets

attrSets - the modifications to make to matching sets

Throws:

RemoteException

getLookupGroups

public String[] getLookupGroups()
                         throws RemoteException

Get the list of groups to join. An empty array means the service joins no groups (as opposed to "all" groups).

Specified by:

getLookupGroups in interface JoinAdmin

Returns:

an array of groups to join. An empty array means the service joins no groups (as opposed to "all" groups).

Throws:
