+/**
+ * A resource filter param is a concise way to express a route query parameter.
+ * Resource filter params abstract away a route's query parameter
+ * interface, treating a query param as a simple attribute on a route instance.
+ * Getting the attribute value is equivalent to looking up the associated query
+ * parameter.  Setting the attribute is equivalent to transitioning to the route
+ * and passing the associated query parameter value.
+ *
+ * Additionally, resource filter params may declare `allowedValues`, an array
+ * containing the set of values the parameter may take.  While unenforced,
+ * `allowedValues` are useful metadata about a resource filter and may be fetch
+ * via `ResourceFilterParamHelper`.  An optional default value may be specified
+ * via `defaultValue` passed to the decorator.
+ *
+ * @see ResourceFilterParamHelper
+ *
+ * @example
+ *
+ *   export default class MyRoute extends Route {
+ *
+ *     @resourceFilterParam(['active', 'pending'], ['active'])
+ *     status;
+ *
+ *     @action
+ *     changeStatus(status) {
+ *       // Sets query param `filter-status` on the current route, which occurs
+ *       // via a route transition.
+ *       this.status = status;
+ *       // Log the value of query param `filter-status`.
+ *       log(this.status);
+ *     }
+ *   }
+ *
+ */

+   * @param {string} name
+   * @param {object} descriptor
+   * @return {object{get, set}}
