Interface Hook
public interface HookProvides the ability to provide pre-execution and post-execution methods bracketing the execution of any
Data API or annotated method.
An instance of Hook is assigned to an instance of Data at the creation of
the Data instance. This is done by passing the Hook instance as an argument to the
getData method of DataFactory that is being called to create the
Data instance.
