Example 1 with QueryResultBatch

use of com.google.datastore.v1.QueryResultBatch in project google-cloud-java by GoogleCloudPlatform.

the class DatastoreTest method buildResponsesForQueryPaginationWithLimit.

    Entity entity4 = Entity.newBuilder(KEY4).set("value", StringValue.of("value")).build();
    Entity entity5 = Entity.newBuilder(KEY5).set("value", "value").build();
