Example 1 with SyncQueriesStartedEvent

use of com.amplifyframework.datastore.events.SyncQueriesStartedEvent in project amplify-android by aws-amplify.

the class SyncProcessor method hydrate.

/**
 * The task of hydrating the DataStore either succeeds (with no return value),
 * or it fails, with an explanation.
 * @return An Rx {@link Completable} which can be used to perform the operation.
 */
Completable hydrate() {
    final List<Completable> hydrationTasks = new ArrayList<>();
    List<ModelSchema> modelSchemas = new ArrayList<>(modelProvider.modelSchemas().values());
    // And sort them all, according to their model's topological order,
    // So that when we save them, the references will exist.

    }
    return Completable.concat(hydrationTasks).doOnSubscribe(ignore -> {
        // This is where we trigger the syncQueriesStarted event since
        // doOnSubscribe means that all upstream hydration tasks
        // have started.

Example 2 with SyncQueriesStartedEvent
