Class Page<T,R>

java.lang.Object
com.amazonaws.services.dynamodbv2.document.Page<T,R>
Type Parameters:
T - item type
R - low level result type
All Implemented Interfaces:
Iterable<T>
public abstract class Page<T,R> extends Object implements Iterable<T>
A page contains a list of items; accessing methods on the list are guaranteed to be purely in-memory operations that will not block or throw exceptions because of transient network issues. A page also knows whether it has a "next page", and if so knows how to retrieve it (which will almost certainly involve a remote network call that may block or fail).
