WTException

members

public Enumeration members()
                    throws WTException

Supported API: true

Overrides:

members in class WTGroup

Enumeration

Throws:

WTException

getService

public FederatedService getService()
                            throws wt.federation.FederationServicesException

Return the service object referenced by the serviceId attribute.

Supported API: true

Specified by:

getService in interface Federated

Returns:

FederatedService

Throws:

wt.federation.FederationServicesException

preset

public void preset()
            throws wt.federation.FederationServicesException

This method is called when a proxy object is first created by a service, just after the object is instantiated and its readExternal method has been called to populate its properties from attributes obtained from the remote information source. This method allows the proxy object to do further class-specific initialization.

Supported API: true

Specified by:

preset in interface Federated

Throws:

wt.federation.FederationServicesException

refresh

public void refresh()
             throws wt.federation.FederationServicesException

Refresh the derived attributes of the object.

Supported API: true

Specified by:

refresh in interface Federated

Throws:

wt.federation.FederationServicesException

refreshIfStale

public void refreshIfStale()
                    throws wt.federation.FederationServicesException

Refresh the derived attributes of the object, but only if the properties are stale.

Supported API: true

Specified by:

refreshIfStale in interface Federated

Throws:

wt.federation.FederationServicesException

update

public void update()
            throws wt.federation.FederationServicesException

Update the derived attributes of the object on the source service.

Supported API: true

Specified by:

update in interface Federated

Throws:

wt.federation.FederationServicesException

prepareForStore

public void prepareForStore()
                     throws wt.federation.FederationServicesException

The persistence manager calls this method just before storing the proxy object in the database. This gives the object an opportunity to make associated proxy objects persistent, if necessary.

Supported API: true

Specified by:

prepareForStore in interface Federated

Throws:

wt.federation.FederationServicesException

findLinks

public QueryResult findLinks(Class targetLinkClass,
                             String obj1Role,
                             Persistable obj2)
                      throws wt.federation.FederationServicesException

Return all link objects that exist between the Federated object and the specified source object.

Supported API: true

Specified by:

Returns:

QueryResult

Throws:

wt.federation.FederationServicesException

                     throws wt.federation.FederationServicesException
