use of com.amplifyframework.datastore.DataStoreConflictHandler.ConflictResolutionDecision in project amplify-android by aws-amplify.

the class ConflictResolver method resolve.

@NonNull
<T extends Model> Single<ModelWithMetadata<T>> resolve(@NonNull PendingMutation<T> pendingMutation, @NonNull AppSyncConflictUnhandledError<T> conflictUnhandledError) {
    final DataStoreConflictHandler conflictHandler;
    try {
        conflictHandler = configurationProvider.getConfiguration().getConflictHandler();
    } catch (DataStoreException badConfigurationProvider) {
        return Single.error(badConfigurationProvider);
    }
    ModelWithMetadata<T> serverData = conflictUnhandledError.getServerVersion();
    ModelMetadata metadata = serverData.getSyncMetadata();
    T local = getMutatedModelFromSerializedModel(pendingMutation);
    T remote = getServerModel(serverData, pendingMutation.getMutatedItem());
    ConflictData<T> conflictData = ConflictData.create(local, remote);
    return Single.<ConflictResolutionDecision<? extends Model>>create(emitter -> conflictHandler.onConflictDetected(conflictData, emitter::onSuccess)).flatMap(decision -> {
        @SuppressWarnings("unchecked") ConflictResolutionDecision<T> typedDecision = (ConflictResolutionDecision<T>) decision;

    });
