Examples with LocalStorageAdapter com.amplifyframework.datastore.storage.LocalStorageAdapter used on opensource projects

Example 1 with LocalStorageAdapter

use of com.amplifyframework.datastore.storage.LocalStorageAdapter in project amplify-android by aws-amplify.

the class MutationProcessorTest method setup.

/**
 * A {@link MutationProcessor} is being tested. To do so, we arrange mutations into
 * an {@link MutationOutbox}. Fake responses are returned from a mock {@link AppSync}.
 * @throws AmplifyException When loading SchemaRegistry
 */

    this.mutationOutbox = new PersistentMutationOutbox(localStorageAdapter);
    VersionRepository versionRepository = new VersionRepository(localStorageAdapter);
    Merger merger = new Merger(mutationOutbox, versionRepository, localStorageAdapter);

Example 2 with LocalStorageAdapter

use of com.amplifyframework.datastore.storage.LocalStorageAdapter in project amplify-android by aws-amplify.

the class MutationPersistenceInstrumentationTest method obtainLocalStorageAndValidateModelSchema.

/**
 * Prepare an instance of {@link LocalStorageAdapter}. Evaluate its
 * emitted collection of ModelSchema, to ensure that
 * {@link PendingMutation.PersistentRecord} is among them.
 *
 * TODO: later, consider hiding system schema, such as the
 * {@link PendingMutation.PersistentRecord}, from the callback. This schema might be
 * an implementation detail, that is working as a leaky abstraction.
 *
 * @throws AmplifyException On failure to initialize the storage adapter,
 *                          or on failure to load model schema into registry
