InteractionLayerTracker
Provides access to the current InteractionLayer .
The bottom-most interaction "layer" can be thought of as a short-lived session with the database. A new layer can be started, for example using the org.apache.causeway.applib.services.sudo.SudoService , or the InteractionService . These allow the user (or the clock or other environmental aspects) to be temporarily altered - similar to a "su" command in Unix.
