Method Details

service

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.

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.

_internalObserve

protected abstract void _internalObserve(Event event,
 javax.jcr.Session liveSession)
                                  throws javax.jcr.RepositoryException

Observes the event with access to the live workspace.

Parameters:
