Examples with EntityQuery com.google.cloud.datastore.EntityQuery used on opensource projects

Example 1 with EntityQuery

use of com.google.cloud.datastore.EntityQuery in project java-docs-samples by GoogleCloudPlatform.

the class Guestbook method getGreetings.

public List<Greeting> getGreetings() {
    // This query requires the index defined in index.yaml to work because of the orderBy on date.
    EntityQuery query = Query.entityQueryBuilder().kind("Greeting").filter(hasAncestor(key)).orderBy(desc("date")).limit(5).build();
    QueryResults<Entity> results = getDatastore().run(query);
    Builder<Greeting> resultListBuilder = ImmutableList.builder();
    while (results.hasNext()) {
        resultListBuilder.add(new Greeting(results.next()));
    }
    return resultListBuilder.build();
}
