-// MockModelTypeStore is implementation of ModelTypeStore that does nothing.

-// By default all methods return SUCCESS and empty results. It is possible to
-// register custom handlers for certain functions to override behavior. It is
-// responsibility of handler to post callback with result.
-// Here is an example:
-// ===
-// void OnReadData(const ModelTypeStore::IdList& id_list,
-//                 const ModelTypeStore::ReadAllDataCallback& callback) {
-//   // Verify id_list here.
-//   // Prepare fake response.
-//   std::unique_ptr<ModelTypeStore::RecordList> record_list(
-//       new ModelTypeStore::RecordList);
-//   record_list->push_back(ModelTypeStore::Record("id1", "value1"));
-//   base::ThreadTaskRunnerHandle::Get()->PostTask(
-//       FROM_HERE, base::Bind(callback, Result::SUCCESS,
-//                             base::Passed(record_list)));
-// }
-//
-// MockModelTypeStore mock_model_type_store;
-// mock_model_type_store.RegisterReadDataHandler(base::Bind(&OnReadData));
-// ModelTypeStore::IdList id_list;
-// id_list.push_back("id1");
-// mock_model_type_store.ReadData(id_list, base::Bind(&ReadDone));
-// ===
-// TODO(pavel): When in-memory store is available this class should delegate all
-// calls to it instead of returning empty successful results.
