## Interface ParameterNameAware

- All Known Subinterfaces:
    ParameterNameAware

      public interface ParameterNameAware

  This interface is implemented by actions that want to declare acceptable parameters. Works in conjunction with `ParametersInterceptor`. For example, actions may want to create a white list of parameters they will accept or a blacklist of parameters they will reject to prevent clients from setting other unexpected (and possibly dangerous) parameters.
