Method Detail

objectRefreshed

public void objectRefreshed(java.lang.Object refreshedObject)

callback that is made when this particular object has been refreshed. the argument to the callback is the object used to register this listener with the RefreshManager. objects should use this as a warning that persistent data in the object may have changed, so they should resync transient caches, etc.

objectDeleted

public void objectDeleted(ObjectId deletedObject)

callback that is made when this particular object has been deleted. the argument to the callback is the object used to register this listener with the RefreshManager.

getPriority

public int getPriority()

returns the relative priority of this listener. This allows clients to control the order that refresh callbacks are made wherever needed
