## Interface ParameterValueAware

- All Known Subinterfaces:
    ParameterValueAware

      public interface ParameterValueAware

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