Interface RegionListener

All Known Subinterfaces:
RegionController

public interface RegionListener

This Listener is invoked when a nested Region is being processed by it's containee. This allows lifecycle implementations to be notified of events when a regionController is being refreshed or validated so that they can take over calling of nested regionController's refresh of validate operations. ADF bindingContainer implementation will make sure that the RegionController registered with the bindingContainer is invoked at the end of all RegionListeners registered with it for both refresh and validate operations.
