Example 1 with QueryResultPage

use of com.amazonaws.services.dynamodbv2.datamodeling.QueryResultPage in project BridgeServer2 by Sage-Bionetworks.

the class DynamoNotificationTopicDao method listTopics.

@Override
public List<NotificationTopic> listTopics(String appId, boolean includeDeleted) {
    checkNotNull(appId);
    // Consistent reads is set to true, because this is the table's primary key, and having reliable tests is more
    // important than saving a small amount of DDB capacity.

    hashKey.setAppId(appId);
    DynamoDBQueryExpression<DynamoNotificationTopic> query = new DynamoDBQueryExpression<DynamoNotificationTopic>();
