public void service(ServiceManager manager)
             throws ServiceException

Specified by:

service in interface Serviceable

Throws:

ServiceException

getPriority

public int getPriority(Event event)

Description copied from interface: Observer

Retrieves the priority to observe this event.
This can be used to process a supported event before others observers.

Specified by:

getPriority in interface Observer

Parameters:

event - the event.

Returns:

the priority where 0 the max priority and Integer.MAX_VALUE the min priority.

supports

public boolean supports(Event event)

Description copied from interface: Observer

Checks if the event is supported. If true, the observe(Event) method will be called.

Specified by:

supports in interface Observer

Parameters:

event - the event.

Returns:

true for observing this event, false otherwise.

observe

public void observe(Event event,
                    Map<String,Object> transientVars)
             throws Exception

Description copied from interface: Observer

Observes an event.

Specified by:

observe in interface Observer

Parameters:

event - the event.

transientVars - transientVars passed from one Observer to another when processing a single Event. This may allow optimizations between observers.

Throws:

Exception - if an error occurs. All exceptions will be logged but not propagated, as the observation mechanism should never fail.

testFrontOfficesDatasources

public Map<String,Map<String,Map<String,Object>>> testFrontOfficesDatasources(List<String> populationIds)
                                                                                         throws Exception

This method will call every front-office and will ask them to test the datasources implied by the chosen populations

Parameters:

populationIds - The chosen populations. Cannot be null.

Returns:

The error messages

Throws:

Exception - If an error occurred while testing
