Enclosing interface:

ClientService

public static interface ClientService.ServiceStateListener

Listener for events that the availability of an ADEPT2Service has changed.

Method Summary

Modifier and Type	Method and Description
void	isAvailable(java.lang.Class<? extends ADEPT2Service> serviceClass, java.net.URI[] serviceUri, ADEPT2Service service, long startTime) Notifies that the designated ADEPT2Service is available (again).
void	isUnavailable(java.lang.Class<? extends ADEPT2Service> serviceClass, java.net.URI[] serviceUri, ADEPT2Service service, long lastStartTime) Notifies that the designated ADEPT2Service is unavailable.

Method Detail

isAvailable

void isAvailable(java.lang.Class<? extends ADEPT2Service> serviceClass,
                 java.net.URI[] serviceUri,
                 ADEPT2Service service,
                 long startTime)

Notifies that the designated ADEPT2Service is available (again). Note that the URIs may have changed while the service was unavailable. This method is also called in case the URIs changed. In such a case, the service has become unavailable for some time but this unavailability may have happened unnoticed.
Implementations should not perform long-running tasks, since that would block notifications for other listeners.

Parameters:

serviceClass - The interface of the ADEPT2Service which is available (again).

serviceUri - The (new) URIs of the ADEPT2Service which is available (again).

service - The service which is available again.

startTime - The start time of the designated service (return value of ADEPT2Service.ping()).

isUnavailable

void isUnavailable(java.lang.Class<? extends ADEPT2Service> serviceClass,
                   java.net.URI[] serviceUri,
                   ADEPT2Service service,
                   long lastStartTime)

Notifies that the designated ADEPT2Service is unavailable. Note that you usually cannot access the service implementation since the underlying service is unavailable.
Implementations should not perform long-running tasks, since that would block notifications for other listeners.

Parameters:

serviceClass - The interface of the ADEPT2Service which is unavailable.

serviceUri - The (new) URIs of the ADEPT2Service which is unavailable.

service - The service which is unavailable.

lastStartTime - The last start time of the designated service (return value of ADEPT2Service.ping()). 0 indicates a starting service, -1 a terminated service and Long.MIN_VALUE a connection problem.
