Example 6 with GraphQLRequest

use of com.amplifyframework.api.graphql.GraphQLRequest in project amplify-android by aws-amplify.

the class SyncProcessor method syncModel.

/**
 * Sync models for a given model class.
 * This involves three steps:
 *  1. Lookup the last time the model class was synced;
 *  2. Make a request to the AppSync endpoint. If the last sync time is within a recent window
 *     of time, then request a *delta* sync. If the last sync time is outside a recent window of time,
 *     perform a *base* sync. A base sync is preformed by passing null.
 *  3. Continue fetching paged results until !hasNextResult() or we have synced the max records.
 *
 * @param schema The schema of the model to sync
 * @param syncTime The time of a last successful sync.
 * @param <T> The type of model to sync.
 * @return a stream of all ModelWithMetadata&lt;T&gt; objects from all pages for the provided model.
 * @throws DataStoreException if dataStoreConfigurationProvider.getConfiguration() fails
