This method calls the intercepted.performAction and if overridden can suppress the default behaviour of the flow and execute something else.
This method calls the intercepted.performAction and if overridden can suppress the default behaviour of the flow and execute something else. It is useful for exploration and debugging work flows, when a user wants to temporarily change the behaviour without touching the main code.
By default it calls intercepted.performAction.

same value as the intercepted action.
This action can be added to the flow over an existing action, it will be scheduled instead of it and can override or intercept the behaviour of an action. This is useful when additional behaviours need to be added. Examples: register as spark temp views for sql, logging filtering, persisting to disk, dredging, etc.
