Class HybridQueryResults<T>

java.lang.Object

com.googlecode.objectify.impl.HybridQueryResults<T>

All Implemented Interfaces:

com.google.cloud.datastore.QueryResults<T>, Iterator<T>

public class HybridQueryResults<T>
extends Object
implements com.google.cloud.datastore.QueryResults<T>

Converts keys-only query results into hybrid query results. This involves chunking the keys into batches and loading each from the datastore. Care is taken to preserve cursor behavior and filter null results (possible due to both the time delay between the query and the load).
