-
-// A service that can be used to query the list of facets that are affiliated
-// with a given facet, i.e., facets that belong to the same logical application.
-// See affiliation_utils.h for details of what this means.
-//
-// The service must be accessed from the UI thread, and it can be utilized in
-// two ways:
-//
-//   1.) On-demand fetching: For the one-off query that wishes to learn
-//       affiliations of facet X when (potentially) issuing an on-demand
-//       network request to the Affiliation API containing the URI of facet X
-//       is acceptable from the privacy and/or performance perspective.
-//
-//       This mode of operation is achieved by invoking GetAffiliations() with
-//       StrategyOnCacheMiss::FETCH_OVER_NETWORK.
-//
-//   2.) Proactive fetching: For the compound query that is concerned with
-//       checking, over time, whether or not each element in a sequence of
-//       facets, W_1, W_2, ..., W_n, is affiliated with a fixed facet Y; and
-//       when it is desired, for privacy and/or performance reasons, that only
-//       facet Y be looked up against the Affiliation API and that subsequent
-//       requests regarding each W_i not trigger additional requests.
-//
-//       This mode of operation can be useful when, for example, the password
-//       manager has credentials stored for facet Y and wishes to check, for
-//       each visited web site W_i, whether these credentials should be offered
-//       to be autofilled onto W_i.
-//
-//       Example code:
-//
-//       class ExampleAffiliatedCredentialFiller
-//           : public base::SupportsWeakPtr<...> {
-//        public:
-//         ExampleAffiliatedCredentialFiller(AffiliationService* service,
-//                                           const FacetURI& y)
-//             : service_(service), y_(y) {
-//           cancel_handle_ = service_->Prefetch(y_, base::Time::Max());
-//         }
-//
-//         ~ExampleAffiliatedCredentialFiller() { cancel_handle_.Run(); }
-//
-//         void ShouldFillInto(const FacetURI& wi, FillDelegate* delegate) {
-//           service_->GetAffiliations(wi, StrategyOnCacheMiss::FAIL,
-//               base::Bind(
-//                   &ExampleAffiliatedCredentialFiller::OnAffiliationResult,
-//                   AsWeakPtr(),
-//                   delegate));
-//         }
-//
-//         void OnAffiliationResult(FillDelegate* delegate,
-//                                  const AffiliatedFacets& results,
-//                                  bool success) {
-//           if (success && std::count(results.begin(), results.end(), y_))
